Voters face November midterms for Congress, local posts and ballot measures as gun-rights and gun-control groups pour funds into pivotal House and Senate contests. Control organizations enjoy a spending lead from Michael Bloomberg support amid a National Rifle Association political slump, while Democrats require four Senate gains including in Donald Trump 2024 states to seize the majority from Republicans.

Gun policy defines Senate battles in Texas, Michigan and South Carolina, House races where groups also spend big, and standalone ballot questions. Everytown for Gun Safety and Giffords will put $10 million into ads; the NRA still funds selected candidates despite historically low fundraising.
