Climate change was one of voters’ top reasons to support Harris over Trump. Polls of the 2024 electorate, both before and after the election, have consistently found that abortion and climate change were Harris’s clearest issue strengths against Trump. Of the issues named in the survey, climate change ranked on par with Project 2025, abortion, and January 6th as the clearest rationales to support Harris rather than Trump: the attack on the U.S. Capitol on January 6th, 2021 – Harris +21; the proposals within Project 2025 – Harris +21; U.S. efforts to fight climate change – Harris +20; the status of abortion laws in the U.S. – Harris +18.
