Background
Brett Kavanaugh is an Associate Justice of the US Supreme Court, appointed by President Trump in 2018 after a contested confirmation process involving sexual assault allegations, which he denied. He joined the court's six-justice conservative supermajority but has at times been a swing vote on procedural and administrative questions, distinguishing him from the three-justice bloc of Thomas, Alito, and Gorsuch on certain issues.
In the context of the 2026 midterms, Kavanaugh's positions carry outsized weight because the court is expected to rule before its summer recess on at least three cases with direct electoral consequences: Watson v. RNC (mail ballot grace periods), Louisiana v. Callais (Voting Rights Act Section 2 scope), and NRSC v. FEC (party-candidate spending coordination limits). His vote in Watson v. RNC was watched closely; he joined the conservative majority questioning mail voting rules.
Kavanaugh has previously written separately to flag concerns about courts interfering with election administration close to polling dates, a principle that could affect the implementation timing of any rulings on the Trump ballot executive order. That doctrine, sometimes called the 'Purcell principle', gives him additional influence over when court-ordered changes to voting procedures can actually take effect.
