Montana votes to ban corporate political money. Next stop? Probably the Supreme Court

Montana voters approved a ballot measure banning corporate political spending, setting up a constitutional clash that could reach the Supreme Court. The initiative directly challenges the 2010 Citizens United ruling, which barred restrictions on independent corporate and union election expenditures. Supporters cast the vote as a state-level rebuke of that precedent, while opponents are expected to argue the ban violates First Amendment protections for corporate speech. The outcome matters because a favorable appellate ruling could give the high court a fresh vehicle to revisit Citizens United. Watch for legal challenges to the measure and whether other states pursue similar bans.
