This appeal requires us to address questions of first impression concerning the construction and constitutionality of two recently-enacted federal firearms laws, 18 U.S.C. § 922(g)(8) and 18 U.S.C. § 922(g)(9), both of which were intended to help curb the escalating societal problems associated with domestic violence. We conclude that these statutory provisions withstand the appellant’s vigorous challenge.
I
In the early morning hours of May 16, 1997, defendant-appellant Christopher Meade began pounding on the door of his estranged wife’s apartment in Lynn, Massachusetts, threatening to shoot her. When police arrived, they discovered a number of persons, including Meade himself, gathered outside the dwelling. The officers instructed all those at the scene to lie face down and display their hands. Instead of obeying, Meade crouched by the side of a parked car and thrust his hand into it. The police later retrieved a loaded handgun from the automobile. Neither the handgun nor the ammunition had been manufactured in Massachusetts.
A recently-enacted federal law makes it a crime for a person who is subject to a judicial anti-harassment or anti-stalking order to possess firearms that have been shipped or transported in interstate commerce. See 18 U.S.C. § 922(g)(8) (quoted infra note 3). Another recently-enacted federal law makes it a crime for a person who has committed a “misdemeanor crime of domestic violence” to possess such a *218 weapon. See 18 U.S.C. § 922(g)(9). Meade ran afoul of both proscriptions: on May 16, 1997, he had a prior misdemeanor conviction for assaulting his spouse, and he was subject to a state court restraining order, issued pursuant to Mass. Gen. Laws ch. 209A, prohibiting contact with her. Consequently, the United States charged Meade with having violated sections 922(g)(8) and (9). A jury found him.guilty on both counts and the district court imposed a 78-month incarcerative sentence. Meade now appeals.
II
Defying numerical order, we start with 18 U.S.C. § 922(g)(9). In relevant part, this statute renders it “unlawful for any person ... who has been convicted in any court of a misdemeanor crime of domestic violence” to possess “any firearm or ammunition ... which has been shipped or transported in interstate or foreign commerce.” The appellant, whose only potential predicate offense is a misdemeanor conviction under a general assault and battery statute, Mass. Gen. Laws ch. 265, § 13A, claims that the district court erred in treating that conviction as a “misdemeanor crime of domestic violence” within the purview of 18 U.S.C. § 922(g)(9).
The linguistic hook upon which Meade fastens this claim appears in an ancillary definitional statute, 18 U.S.C. § 921(a)(33)(A), which characterizes a “misdemeanor crime of domestic violence” as an offense that is a misdemeanor under state law,
see id.
§ 921 (a) (33) (A.) (i), and which “has, as an element, the use or attempted use of physical force, or the threatened use of a deadly weapon, committed by a current or former spouse, parent, or guardian of the victim, by a person with whom the victim shares a child in common, by a person who is cohabiting with or has cohabited with the victim as a spouse, parent, or guardian, or by a person similarly situated to a spouse, parent, or guardian of the victim,”
id.
§ 921(a)(33)(A)(ii). Meade acknowledges that his prior conviction satisfies the first criterion (i.e., it was for a misdemeanor), but insists that it fails to satisfy the second criterion because the underlying statute does not have
as an element
the relationship status between misdemeanant and victim. As the appellant sees it, the only crimes that fit within the quoted language (and, thus, the only crimes that may serve as predicate offenses for purposes of section 922(g)(9)) are those which, as part of their formal definition, require a showing of both the mode of aggression (e.g., the use of a weapon) and the assailant’s relationship status (e.g., spouse). The district court rejected this exercise in statutory interpretation,
see United States v. Meade,
Meade’s argument depends on the answer to the following question: Did Congress intend that only misdemeanors which include the relationship status as an element within their formal definition would count as predicate offenses under section 922(g)(9)? Our search for this answer must begin with the language that Congress used in crafting the statutory scheme. See United States v. Charles George Trucking Co., 823 F.2d 685, 688 (1st Cir.1987). That perspective focuses our attention on the word “element” in the text of section 921(a)(33)(A)(ii). This singular noun is followed not by one, but by two conceptually distinct attributes: the mode of aggression and the perpetrator’s relationship to the victim. Meade’s gloss on the reach of the word “element” indiscriminately conflates the two.
We reject this gloss. In construing statutes, courts should presume, absent contrary evidence, that Congress knew, and meant to adopt, the background legal concepts associated with the words that it chose to incorporate into a law. See
Morissette v. United States,
We could well end our interpretive inquiry at this juncture. When, as now, the plain language of a statute unambiguously reveals its meaning, and the revealed meaning is not eccentric, courts need not consult other aids to statutory construction.
See Salinas v. United States,
The statute’s legislative history is particularly helpful in this regard. In describing the interrelationship between section 922(g)(9) and other gun-control laws on the Senate floor, the legislation’s chief sponsor noted presciently that “convictions for domestic violence-related crimes often are for crimes, such as assault, that are not explicitly identified as related to domestic violence.” 142 Cong. Rec. S11878 (1996) (statement of Sen. Lautenberg). For this reason, he urged local law enforcement authorities administering gun registration provisions “to thoroughly investigate misdemeanor convictions on an applicant’s criminal record to ensure that none involves domestic violence, before allowing the sale of a handgun.” Id. These statements, made by the principal architect of 1 the bill before final passage, clearly demonstrate Congress’s threshold understanding that “misdemeanor crimefs] of domestic violence” would not be limited to those in which the relationship status was included as a formal element of the statute of conviction.
There are, of course, limitations on the extent to which courts appropriately may rely on the statements of individual legislators to color the meaning of statutory language.
See, e.g., Regan v. Wald,
*220
We note, too, that plain language can be made more (or less) compelling by a frank consideration of possible alternatives. Reading section 922(g)(9) in the manner that the appellant advocates would lead to a significant practical anomaly and would frustrate the clear purpose behind the law, which contemplated that the ban on firearms possession would apply broadly to all those falling into the relevant categories.
See
18 U.S.C. § 922(g)(9) (making it “unlawful for
any
person ... who has been convicted in
any
court of a misdemeanor crime of domestic violence” to possess
“any
firearm or ammunition”) (emphasis supplied);
see also Barrett v. United States,
The appellant counters this statutory analysis with an array of asseverations, none of which we find persuasive. First, he maintains that had Congress intended not to require relationship status to be a formal element of a misdemeanor crime of domestic violence, it could have written the law differently (to say, for instance, that such a crime is an offense that “has, as an element” the use of force or a weapon, “and was committed by” someone within a relevant relationship). But Congress is not required to draft statutes in ways that are precise to the point of pedantry. As long as a statute, as written, is reasonably clear and does not lead to absurd outcomes, courts should construe it according to its tenor.
See Salinas,
Next, the appellant directs our attention to several statutes — including solicitation and sentence-enhancement laws — in which Congress has employed a more or less comparable linguistic structure that defines a “crime of violence” as an offense that “has as an element” the use or threatened use of force or of a deadly weapon against the person or property of another.
See, e.g.,
18 U.S.C. §§ 16(a), 373(a), 521(c)(2), 924(c)(3)(A), 924(e)(2)(B)®, 3156(a)(4)(A), 3559(c)(2)(F)(ii). In the appellant’s view, such statutes routinely collapse the mode and object of aggression into a single element, and, thus, suggest that section 921(a)(33)(A)(ii) should be construed to encompass both mode of aggression and relationship status under the “element” rubric. It is true, of course, that Congress’s use of parallel language and construction in different statutes may at times inform judicial interpretation.
See Irving v. United States,
First, Congress has made manifest its intent, and there is no need to resort to other aids (including other statutes) for assistance in the interpretive process.
See Norfolk & W. Ry. Co. v. American Train Dispatchers’ Ass’n,
The appellant has a fallback position. He notes that courts by and large have taken a so-called categorical approach in construing statutes and sentencing guidelines that incorporate “predicate offense” concepts.
See, e.g., Taylor,
The task before the
Taylor
Court was to determine the precise meaning of the term “burglary” as used in a sentence-enhancement statute, 18 U.S.C. § 924(e). After reviewing the relevant legislative history, the Court determined that Congress meant the term to carry a generic definition.
See Taylor,
The Taylor Court’s sequencing of the two inquiries that we have described explodes Meade’s argument. Before engaging in a categorical approach, one first must have established the formal definition of the particular predicate offense, a pro-_ cess that necessarily requires determining the requisite elements of the statute of conviction. The appellant’s attempt to establish the formal definition of a “misdemeanor crime of domestic violence” by direct resort to a categorical approach thus puts the cart before the horse. 1
*222
The appellant next contends that section 922(g)(9) is unconstitutionally vague because it does not define the offense with sufficient clarity that an ordinary person can ascertain whether his actions would fall within its proscriptions. We reject this contention out of hand. Criminal statutes are unconstitutionally vague if they do not adequately specify the conduct that they prohibit or the class of persons to whom they apply.
See, e.g., United States v. Lanier,
As a final matter, the appellant argues that the rule of lenity should weigh in his favor. The rule of lenity has bearing only if, after a full examination of a particular statute, an inquiring court must guess at what Congress intended.
See Holloway v. United States,
— U.S.—,—n. 14,
Ill
Those convicted of misdemeanors in Massachusetts do not automatically lose their civil rights upon conviction.
See United States v. Indelicato,
A major, and dispositive, problem with this asseveration is that the appellant has waived it and, accordingly, there is no error to review.
See United States v. Olano,
As a general matter, a criminal defendant who stipulates to an element of an offense relinquishes his right to test the government’s case with respect-to the existence of the facts underlying that particular.
See United States v. Hardin,
To assert that a stipulation to an element of a crime does not affect legal defenses is to build an artificial wall between factual and legal arguments. The prosecution’s successful establishment of an element of a crime does not invariably depend on showing merely that a certain set of facts exist; there are often legal barriers to scale as well. This case illustrates the point: establishing the predicate misdemeanor crime of domestic violence hinged not only on producing an official record attesting to an underlying conviction, but also on overcoming whatever legal defenses Meade mounted in regard to the materiality of that conviction. Given that reality, and given the corollary fact that criminal defendants frequently gain strategic benefits from entering into stipulations,
see, e.g., Old Chief v. United States,
This rule governs here. There was not the slightest indication at any point in the proceedings below that Meade intended to raise or preserve any legal defenses apart from Ms “relationship status” defense. To the precise contrary, the totality of the circumstances (especially Meade’s stipulation to the predicate offense, his acquiescence in the jury instructions that followed, and his affirmative preservation of a different legal defense) compels a determination that Meade relinquished all other defenses, factual and legal, pertaining to the stipulated element.

*224
We therefore rebuff Meade’s suggestion that his newly-minted restoration of rights defense was left open by the parties,
sub silentio,
to be addressed at a later date. That defense was waived.
See United States v. Valenzuela,
IV
Having repulsed the appellant’s attacks on 18 U.S.C. § 922(g)(9), we turn now to 18 U.S.C. § 922(g)(8). Meade raises two constitutional challenges to this provision.
First, Meade asserts that section 922(g)(8) affronts the Tenth Amendment, U.S. Const, amend. X, because it promotes interference by the federal government in state civil proceedings. The United States responds that the statute requires proof, in each and every case, that the firearm in question was transported or sold in interstate commerce. See infra note 3. Thus, the government reasons, enactment of the statute falls within Congress’s regulatory power under the Commerce Clause, U.S. Const, art. I, § 8, cl. 3.
The Tenth Amendment reserves to the states all powers not vested by the Constitution in the federal sovereign.
See Printz v. United States,
It is true, as the government observes, that courts regularly have upheld the use of a case-by-case jurisdictional element, such as imbues this statutory scheme, as a means of satisfying the required nexus with interstate commerce, and, thus, bringing federal legislation within the shelter of the Commerce Clause.
See, e.g., United States v. Cunningham,
*225
This proposition is simply incorrect. Section 922(g)(8) does not in any way intrude upon state court proceedings, or upon the authority of a state or its agents to administer their domestic relations laws in the manner they see fit. Stripped to bare essence, section 922(g)(8) makes the existence of a state court order an element of a federal misdemeanant-in-possession offense — no more and no less. Nothing in the state court proceeding changes on account of, or is in any way affected by, the operation of the federal law. Thus, section 922(g)(8) is totally devoid of Tenth Amendment implications.
See Bongiomo,
Next, Meade maintains that section 922(g)(8) violates the Due Process Clause because it does not mandate that state court restraining orders inform those whom they enjoin of the federal law consequences that may attach.

The issue of notice, in the constitutional sense, customarily centers around whether a law explains with sufficient clarity the conduct that it purports to criminalize.
See, e.g., Bouie,
that would place an intimate partner in reasonable fear of bodily injury ...; and
(C)(i) includes a finding that such person represents a credible threat to the physical safety of such intimate partner ...; or
(ii) by its terms explicitly prohibits the use, attempted use, or threatened use of physical force against such intimate partner ... that would reasonably be expected to cause bodily injury;
* * *
to ship or transport in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.
The appellant attempts to put a spin on the notice argument by touting
Lambert v. California,
A significant problem with this aspect of the appellant’s argument is that the Court has steadfastly resisted efforts to extend
Lambert’s,
reach,
see, e.g., id.
at 609,
Meade nevertheless tries to bring his case within the
Lambert
exception by arguing that firearms possession is an act sufficiently innocent that no one could be expected to know that he would violate the law merely by possessing a gun. As
Staples v. United States,
In short, we do not believe that the prohibition of section 922(g)(8) involves conduct and circumstances so presumptively innocent as to fall within the narrow confines of the Lambert exception. We therefore reject the appellant’s contention that the statute, on its face, violates due process rights of notice.
y
We need go no further. The first of the firearms statutes at issue here — 18 U.S.C. § 922(g)(9) — is by no means a model of draftsmanship, but the appellant’s gloss upon it cannot be sustained by any reasonable method of statutory interpretation. The second statute, 18 U.S.C. § 922(g)(8), easily withstands the appellant’s multifarious constitutional attacks.
Affirmed.
Notes
. In his effort to convince us to sanction a categorical approach, Meade uses scare tactics. He proclaims, with appropriate rhetori- . cal flourishes, that, unless relationship status *222 is deemed a part of the formal definition of the predicate offense, factfinding will be a "nightmare.” This shark has no teeth. Federal criminal trials typically involve proof and differential factfinding, and the issue of relationship status is by no means outside a jury's. competence.
. In concluding here that stipulation to an element functions as a waiver of legal defenses, we express no opinion on whether the government’s duty to prove each element of a crime beyond a reasonable doubt is diluted impermissibly if the jury instructions do not submit the stipulation for the jury's consideration. This thorny question has divided the courts of appeals,
compare Muse,
. The statute provides in pertinent part:
(g) It shall be unlawful for any person—
(8) who is subject to a court order that—
(A) was issued after a hearing of which such person received actual notice, and at which such person had an opportunity to participate;
(B) restrains such person from harassing, stalking, or threatening an intimate partner of such person ..., or engaging in other conduct
. We note in passing that irony is no stranger to the law: Meade, after arguing that section 922(g)(8) infracts the Tenth Amendment, now posits that it is unconstitutional because it does not require state judges fully to include federal law ramifications in their restraining orders in domestic proceedings.
. For the sake of completeness, we note that although
Lambert
has, in effect, been limited to its rather distinctive facts, the Court at times has reached a similar result by means of statutory interpretation (as opposed to due process). See,
e.g., Ratzlaf v. United States,
