Candidates in key battlegrounds were set to make their last pitches to undecided voters in the final hours before Election Day, as GOP prospects continued to brighten.
Republicans are seen by nonpartisan analysts as the favorites to take the House majority Tuesday, with surveys showing key voting blocs trending away from Democrats as many voters say their top concerns are inflation and economic uncertainty.
Senate control remains a tossup, but polls show GOP candidates in states such as Arizona, New Hampshire and Pennsylvania have made gains in the final weeks.
Democrats were also working to hold on to governors’ offices in Oregon and New York, states that were once seen as safely Democratic but have been competitive this year.
