President Donald Trump campaigned in Grand Island, Nebraska, on Oct. 5, seeking to energize supporters in a state he won by a wide margin in 2024. The rally came four weeks before the Nov. 3 midterm elections, with polls showing Democrats’ prospects of taking control of both the House and Senate have improved compared with several months ago. The contest will test whether Trump’s efforts to rally voters in strong Republican territory can offset concerns about the economy and dissatisfaction with his presidency. The available polling description offered no specific figures, and the political outlook remains uncertain as campaigns enter their final stretch. Control of Congress will shape the agenda facing the next session, including whether the president’s party can advance legislation without opposition control of either chamber. Voters will decide the balance of power on Election Day.
