MEMORANDUM **

Cathleen Cantlon (“Cantlon”) appeals the district court’s order denying her motion for a new trial following her convictions for (1) interstate mailing of a firearm, in violation of 18 U.S.C. § 922(e), and (2) possession of a firearm by a person who has been committed to a mental institution, in violation of 18 U.S.C. § 922(g)(4). Cantlon argues that the possession conviction is invalid under the Fifth Amendment because the Montana Supreme Court subsequently vacated the underlying commitment order and directed the state district court to dismiss it. She further argues that the evidence supporting the possession conviction led to prejudicial spillover on the interstate mailing charge during trial. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

We review for abuse of discretion a district court’s denial of a motion for a new trial under Federal Rule of Criminal Procedure 33. *See United States v. French,*748 F.3d 922, 934 (9th Cir. 2014); Fed. R. Crim. P. 33. Applying the law of analogous felon-in-possession cases *United States v. Padilla,*387 F.3d 1087, 1090-92 (9th Cir. 2004) and *Lewis v. United States,*445 U.S. 55, 60-65, 100 S.Ct. 915, 63 L.Ed.2d 198 (1980), the district court ruled that the dismissal of Cantlon’s commitment order did not operate retroactively to affect her conviction. As a result, her conviction was not invalid. The court also ruled that there was no “prejudicial spillover,” reasoning that the undisputed evidence at trial proved the mailing charge “without any reference whatsoever to [Cantlon’s] mental health condition.” We agree.

1. In challenging her possession conviction, Cantlon’s attempts to distinguish *Padilla*and *Lems*fail. As Cantlon’s counsel conceded at argument, Cantlon had a right to a jury trial. And we conclude that the Montana trial court’s “bare-bone[s]” commitment order was not vacated and dismissed for reasons any less “technical” than those given in *Padilla*and *Lems.*We agree with Cantlon that the burden of proof is lower in involuntary commitment proceedings: clear and convincing evidence is all that is required to prove the existence of a mental disorder. *See In re R.T.,*204 Mont. 493, 665 P.2d 789, 790 (1983). But Cantlon has not explained why that fact should differentiate the instant case, especially in light of the Supreme Court’s reading of the “sweeping” text and “broad” purpose of a similar provision in the same statute at issue here. *Lewis,*445 U.S. at 61, 64-65, 100 S.Ct. 915 (interpreting 18 U.S.C. § 922(g)(1)). At the very least, the district court did not abuse its discretion in applying *Padilla*and *Lewis.*

2. Turning to Cantlon’s mailing conviction, her argument is likewise unpersuasive. Applying the *Lazarenko*factors, the balance of competing considerations do not support a finding of prejudicial spillover. *See United States v. Lazarenko,*564 F.3d 1026, 1044 (9th Cir. 2009). The district court did not abuse its discretion in reaching the same conclusion, especially, as the *491court noted, given the strength of the government’s case.

AFFIRMED.
