On December 14, 1981, a federal district court in Puerto Rico preliminarily enjoined Commonwealth officials from filling a be- . tween-elections vacancy in the Commonwealth’s House of Representatives according to the procedure set forth in the Constitution of the Commonwealth of Puerto Rico. The district judge believed that the constitutionally-mandated procedure, which allows the political party of the representatives whose seat fell vacant to choose his successor, probably violated the federal constitution. Defendants, the Popular Democratic Party (“PDP”) and Hector L. Acevedo, its election commissioner, appeal. We believe that the issuance of a preliminary *2 injunction was erroneous, and we vacate the injunction.
I
The Constitution of Puerto Rico provides that its House of Representatives shall be comprised of 51 members, 40 of whom shall be selected by election from single-member districts and 11 of whom shall be selected at large. The at-large representatives are the 11 persons obtaining the most votes in a Commonwealth-wide election — one in which each voter can vote for only 1 representative. Article III, Section 2 and Section 3.
See Garcia Passalacqua
v.
Tribunal Electoral,
In the general election held on November 4, 1980, Fernando J. Tonos Florenzan, a member of the PDP, was elected an at-large representative. Subsequently, he was disqualified because he was 23 years old — 2 years younger than the minimum age the Constitution prescribes. Article III, Section 5. His seat was declared vacant.
Tonos Florenzan v. Bernazard, 111
D.P.R.-,
On December 10, 1981, before his successor could be selected, 8 registered voters— plaintiffs here — filed suit alleging that the replacement procedure violates the First, Fifth and Fourteenth Amendments to the United States Constitution because it does not provide for a by-election open to all voters regardless of party. They sought a declaratory judgment, an order compelling a by-election and, subsequently, a temporary restraining order (“TRO”).
The district court, while denying the TRO, quickly held a hearing and, on December 14, 1981, it issued a preliminary injunction effectively holding the seat vacant until it could decide the constitutional issue. Defendants appealed. Subsequently, on January 5, 1982, it denied a request to stay the injunction pending appeal. Defendants, noting that the House is divided evenly between the two major parties (25-25) and arguing that the House could not function properly, sought a stay from this court pending decision on their appeal. The issues were briefed effectively by all parties on an expedited schedule and oral argument was heard on January 22, 1982. As the parties agree, the question of whether we should stay the injunction pending appeal raises the same issues as the appeal itself. Hence, we here decide the appeal — the validity of the preliminary injunction.
II
In determining whether a plaintiff is entitled to a preliminary injunction, the court normally considers four criteria, namely, “(1) that plaintiff will suffer irreparable injury if the injunction is not granted; (2) that such injury outweighs any harm which granting injunctive relief would inflict on the defendant; (3) that plaintiff has exhibited a likelihood of success on the merits; and (4) that the public interest will not be adversely affected by the granting of the injunction.”
Planned Parenthood League of Massachusetts v. Bellotti,
*3 A
As the criteria listed above indicate, in deciding whether a preliminary injunction is appropriate, a district judge must engage in a balancing of harms. A preliminary injunction should in the usual ease not issue unless the harm to plaintiff, in its absence, outweighs the harm to defendant that it may cause. The district court wrote that the requisite harm is to be found in the fact that allowing the PDP-selected replacement to take his seat pending resolution of this legal controversy would “moot” the case. It is wrong on this point. This controversy would remain real despite the seating of a replacement — at least until the election of a new representative at the next general election in 1984. Litigation could continue in this ease just as it has in the related case of
Partido Popular Democratico v. Gobernador,
111 D.P.R. -,
The district court also found irreparable harm in the fact that, if plaintiffs later win, the voters would have been subject to laws enacted with the help of an unconstitutionally-selected legislator. This harm would seem at least equally balanced, however, by the interim harm that an injunction would have caused defendants if they later win, for in that case, those who voted for Tonos Florenzan in light of his party affiliation would wrongly have had no representative, see p. 7 and n.5 infra. The PDP would have been deprived of what otherwise appears to be a one-vote majority leaving the House deadlocked with the Governor a member of the major rival party. Indeed, viewed from the point of view of the political parties, the harm to one caused by an injunction “wrongly” (as the case turns out) withheld would seem exactly balanced by the harm to the other caused by an injunction “wrongly” issued. And, the harm to some voters through the possible enactment of laws with the participation of a “wrongly” appointed legislator would seem at the least counterbalanced by the harm to others caused by failure to pass laws (or the passage of other laws) brought about by “wrongly” keeping a seat vacant during the January — April legislative session.
We are aware of no special factors tilting the balance in favor of plaintiffs. To the contrary, the facts that for many years legislators have been chosen in accordance *4 with the challenged constitutional provisions, and that the Supreme Court of the United States has allowed another legislator facing a similar constitutional challenge to sit while that challenge is resolved, (see note 1 supra), suggests that there is no emergency requiring an immediate injunction. Plaintiffs’ ingenious argument that the injunction simply preserves the status quo overlooks the fact that “status quo” in this context should encompass the normal functioning of the legislature and electoral processes in accordance with the provisions of the Constitution of Puerto Rico. Be that as it may, the district court finding that the harm to plaintiffs outweighs that likely imposed upon those whom the injunction affects adversely, is clearly erroneous.
B
We shall go next to plaintiffs’ claim that they are so clearly right on the merits as to warrant injunctive relief even if the harms are no better than evenly balanced.
Cf. Delaware River Port Authority v. Transamerican Trailer Transport, Inc.,
Plaintiffs’ claim that Article III, Section 8 is unconstitutional rests upon two arguments. First, they argue that it violates the First, Fifth and Fourteenth Amendments to the Constitution for a state (or for the Commonwealth) to fill a legislative vacancy by appointment rather than through a by-election — at least where the next general election may be as much as three or four years away. In support, they cite reapportionment cases such as
Reynolds v. Sims,
We are not convinced by these lines of argument for three sets of reasons. First, as plaintiffs admit, none of these authorities directly considers whether it is constitutional to appoint a successor to fill an interim legislative vacancy. According to the undisputed assertion of the defendants, at least 21 states allow legislative vacancies to be filled by the appointment of a successor who will serve until the next general election or the end of the predecessor’s term. Of these, at least 12 require that the appointee be a member of the same political party as his predecessor; and four others allow the political party itself to make the selection. When this type of provision has been challenged, the courts, with one exception, have upheld its validity.
See, e.g.,
*5
Patterson v. Burns,
These courts have reasoned that (1) the long history of filling vacancies by appointment, (2) the need to preserve the political balance obtained in previous general elections, (3) the expense and related inconvenience of calling special elections, (4) the uncertainty about the extent to which, or when, by-elections (with their typically lower turnout, dependency upon timing and different political strategies) are fairer alternatives than waiting until the next general election, (5) the need to assure a single party time to carry out a program, and other similar factors, indicate the wisdom of allowing the states themselves to decide whether, and when, to fill interim vacancies by appointment or by by-election. There is no reason for denying Puerto Rico at least as much discretion or power. That the federal Constitution embodies this wisdom is suggested by the broad language used in relation to the form of a state’s government (“the United States shall guarantee to every State ... a Republican Form of Government,” Article IV, Section 4); by the Tenth Amendment’s reservation to the states of powers not prohibited by the Constitution, and by the
absence
in the Constitution of any language requiring the contrary. Indeed, it was believed necessary to insert
specific
language into the Constitution providing for by-elections in the case of federal senators.
4
There is no such language applicable to state legislatures. (Moreover, even as to the “federal official” language which specifically requires a by-election, the federal courts have upheld the validity of interim appointments with twenty-nine months duration.
Valenti v. Rockefeller,
Thus, considerations of “statutory” interpretation (the absence of any by-election language addressed to the states), practical considerations (cost along with possibly low turnout at by-elections for state legislature), considerations of judicial capacity (the highly subjective nature of determining when an interim appointment is “too long,” given an appointment that is, in any event, bounded by the next general election), and considerations of federalism (state autonomy in determining, within fairly broad limits, the nature of its own political system) all make it likely that these decisions allowing interim appointments to fill state legislative vacancies remain good law.
Second, once it is assumed that an interim appointment process is constitutional, the cases assuring broad participation in the electoral process, such as
Kramer v. Union School District, supra,
and
Williams
v.
*6
Rhodes, supra,
become far less relevant, for they concern participation in elections that are admittedly, in principle, open to all. Similarly, the cases holding that party allegiance is an impermissible criterion for appointment to state office are of little help.
See, e.g., Branti v. Finkel,
One might argue, as a matter of form, that appointment by a governor is indeed more “democratic” because the governor is himself elected. Yet in practice this is likely not to be so when the governor and former representative are of different parties. In that case the party difference is likely to produce successors of different parties. In such circumstances, we see how the framers of a state constitution might conclude that party selection is more likely to reflect the will of the voters than selection by the governor, for it was the former representative’s party, not that of the governor, that won the prior seat. Such a judgment, reflecting a knowledge of political practice, seems perfectly consistent with the basic democratic role of the modern political party — translating the individual wills of myriad voters into a practically achievable program administered by a government that can be held responsible for its performance at the polls.
See Schattschneider, Party Government
1 (1942);
Finer, The Theory and Practice of Modern Government,
627 (1960). Although this type of vacancy selection might be unusual, found in only four states and Puerto Rico, it seems no less fair or democratic in principle than the party primary itself — an essential part of our democratic political system.
See, e.g., Cousins v. Wigoda,
Third, the considerations favoring the constitutionality of party selection to fill an interim legislative vacancy are particularly strong here. Article III, Section 8 of the Constitution of Puerto Rico is part of a broader constitutional scheme designed to increase the likelihood of minority representation in the legislature. See Article III, Section 7. Section 8 provides that each voter in the election for eleven at-large representatives is to have only one vote. Presumably, the two major parties would exhaust most of their voting strength in electing the first 8, 9 or 10 representatives, leaving a minority party with the most votes for the 11th position. Article III, Section 8 complements this provision by stating that in case of vacancy, the party whose candidate won shall select the replacement.
A by-election requirement is inconsistent with the basic purpose of these two articles. A by-election for a minority party vacancy, for example, would almost certainly be won by a major party, for at a by-election (with one position at stake), unlike a general election (with eleven positions at stake), the major party’s votes would not be split.
Plaintiffs argue that these provisions have recently achieved actual minority representation only once, in 1972. Regardless, they are reasonable in theory and continue to make minority representation easier to achieve. Similar “limited voting” provisions have been consistently sustained.
Hechinger v. Martin,
Moreover, given the existence of this voting system, it is understandable why the framers of Article III, Section 8 thought that filling a vacancy by party selection would be fairer than requiring a by-election. For one thing, the voting returns show that individual candidates receive enormous number of votes in a few districts and nearly none in others — a fact suggesting that most voters vote for the party, giving the candidate vast numbers of votes when he is at the head of the list (and “party” votes count in his favor) and hardly any votes when he is not (and voters must vote separately for him by name). 5 (See Appendix.) For another thing, how is a by-election to be structured? If it is Commonwealth-wide, many voters (those outside the districts where Tonos Florenzan appeared at the top of the list) will effectively have been given two votes for representative at-large, for the single person they voted for at the general election will also be sitting. Yet, one cannot readily limit the voting to individual Tonos Florenzan districts, for to do so would deprive those few persons outside of those districts who nonetheless voted for him, of a vote for his replacement. To declare a by-election for all 11 seats is obviously unreasonable, for 10 are not vacant. All this helps to explain why the party selection method for filling interim vacancies appears reasonable.
In sum, this vacancy-filling system appears to be no less fair or democratic than that found in most states; it is nonetheless tailored to the special concerns and political circumstances of the Commonwealth of' Puerto Rico. Certainly, the federal Constitution and the Compact entered into by the Congress with Puerto Rico provide no less autonomy to Puerto Rico than to the states in this regard.
See Calero-Toledo v. Pearson Yacht Leasing Co.,
*8 C
The final factor, “adverse affect upon the public interest,” need not be considered at length. We will, however, note two points. First, in most of the cases in which the courts have examined election practices— including those in which it held the practice unconstitutional — they not only refrained from authorizing preliminary injunctions but they have also carefully tailored any final injunctive relief to avoid interfering with work of sitting legislatures, despite the presence of legislators whose selection was unconstitutional under the ease then decided. This was true in reapportionment
cases
— see
Wise v. Lipscomb,
To put the matter differently, we believe the district court should have given somewhat more weight than it did to the desirability of the legislature’s functioning and the undesirability except in compelling circumstances of a federal court’s intruding through injunctions directly into the Commonwealth’s legislative and political processes.
Cf. Doran v. Salem Inn, Inc.,
Even without these special factors, however, even under the most traditional tests, the preliminary injunction ought not to have issued. We therefore vacate the order of the district court and remand for proceedings consistent with this opinion.
The mandate of this court will issue at the close of business, Tuesday, February 2, 1982.

Notes
. In
Partido Popular Democratico v. Gobernador,
111 D.P.R. -,
. . . the method designed by the lawmaker has no defects with regard to the equal protection of the law. The exclusion of candidates of other parties and of independent candidates does not violate the constitutional • guarantee to the equal protection of the law.
Even assuming that the strict scrutiny rule is applicable, there is compelling public interest directing the lawmaker to consider that the vacant seat belongs to the party who nominated the legislator. Among those compelling interests the following can be singled out: that there be no changes in the legislative balance until the next general election is held, the stability of governmental structures, the protection of the electoral mandate of the previous general election, and the reduction of inter-partisan political campaigns to once every four years.
The Supreme Court of the United States,
sub nom. Rodriquez v. Popular Democratic Party,
noted probable jurisdiction of an appeal from the judgment of the Puerto Rico courts, - U.S.-,
. The district judge, when referring to the likelihood of success in this case, used the phrase, “substantial possibility” of success. Except in the unusual case, however, where the harm to plaintiffs is particularly severe and disproportionate,
see Providence Journal Co. v. Federal Bureau of Investigation,
. In the single exception,
Rudman v. Rini,
. When vacancies happen in the representation of any State in the Senate, the executive authority of such State shall issue writs of election to fill such vacancies: Provided,
That the legislature of any State may empower the executive thereof to make temporary appointments until the people fill the vacancies by election as the legislature may direct.
XVII Amendment.
As to members of the House of Representatives, Article I, Section 2 of the U. S. Constitution provides, “When vacancies happen in the Representation from any State, the Executive Authority thereof shall issue Writs of Election to fill such Vacancies.”
. Mr. Tonos Florenzan received 120,678 votes in the 1980 election and 120,268 of these votes were cast for him in the 21 precincts where he appeared at the top of the PDP ticket. Although he was available to the electors in the rest of the 113 electoral precincts of Puerto Rico, he accumulated only around 400 votes in those other precincts.
. Plaintiffs also argue that the selection process violates the Twenty-Sixth Amendment to the Constitution. Article III, Section 8 specifies that the party select its replacement in the same manner in which the former representative was selected. In this case, the former representative was chosen as a “youth delegate” and the successor-selection process, in plaintiffs’ view, therefore discriminates against the aged. This issue was not raised below, and
*8
it played no part in the district judge’s deliberations. Indeed, the issue apparently was first raised in a brief filed here the day before argument. Defendants have had no opportunity to consider this lately added ground. Therefore we do not pass upon this question. We note, however, that we do not believe plaintiffs’ argument is likely to prove so clearly correct as to warrant issuance of a preliminary injunction. Plaintiffs point to
Terry v. Adams,
. Justice Brennan referred the issue to the full Court.
. Thus, the injunction at issue here cannot prevent at least one “potentially unconstitutional” representative from sitting — an additional fact that makes the district court’s finding of “irreparable harm” in the absence of the injunction surprising.
