Recent polling shows Democrats competitive or leading in multiple states Donald Trump carried by double digits in 2024, including Ohio, Alaska, Iowa, Texas, and Kansas, amid an unfavorable national environment for Republicans tied to presidential approval and economic pressures. These developments have expanded Democratic opportunities to flip Republican-held seats in Trump-won territory. At the same time, Republicans have positioned New Hampshire—a state Kamala Harris carried—as a leading pickup target, with the race rated as a toss-up or lean Republican in several forecasts due to the open Democratic seat. Maine, another Harris state with Republican incumbent Susan Collins, remains competitive but leans Democratic. The combination of outcomes required for an affirmative resolution remains uncertain less than five weeks before Election Day, reflecting the closely contested nature of the overall Senate map.
