His overall approval ratings have slipped to a new low, more Americans than not doubt his mental acuity, and his support against leading Republican challengers is far shakier than at this point four years ago.

Former president Donald Trump leads a still-forming field of candidates for the Republican nomination, receiving about twice as much support as Florida Gov. Ron DeSantis. But Trump carries his own baggage, with a majority saying he should face criminal charges in cases involving efforts to overturn the results of the 2020 election, events leading to the Jan. 6, 2021, attack on the U.S. Capitol by a pro-Trump mob and his handling of classified documents.

Biden announced his reelection campaign barely two weeks ago with a video highlighting the attack on the Capitol, and he focused on Republican efforts to further restrict abortion access, limit LGBTQ rights, ban books and alter school history curriculums.
