WASHINGTON • A majority of Democrats now think one term is plenty for President Joe Biden, despite his insistence that he plans to seek reelection in 2024.

That’s according to a new poll from The Associated Press-NORC Center for Public Affairs Research that shows just 37% of Democrats say they want him to seek a second term, down from 52% in the weeks before last year’s midterm elections.

While Biden has trumpeted his legislative victories and ability to govern, the poll suggests relatively few U.S. adults give him high marks on either. Follow-up interviews with poll respondents suggest that many believe the 80-year-old’s age is a liability, with people focused on his coughing, his gait, his gaffes and the possibility that the world’s most stressful job would be better suited for someone younger.

“I, honestly, think that he would be too old,” said Sarah Overman, 37, a Democrat who works in education in Raleigh, North Carolina. “We could use someone younger in the office.”

As the president gives his State of the Union address Tuesday, he has a chance to confront fundamental doubts about his competence to govern. Biden has previously leaned heavily on his track record to say that he’s more than up to the task. When asked if he can handle the office’s responsibilities at his age, the president has often responded as if he’s accepting a dare: “Watch me.”

Democratic candidates performed better than expected in the 2022 midterm elections, a testament to Biden’s message that he is defending democracy and elevating the middle class. Democrats expanded their control of the Senate by one seat and narrowly lost their House majority even though history indicated there would be a Republican wave.

The decline among Democrats saying Biden should run again for president appears concentrated among younger people. Among Democrats age 45 and over, 49% say Biden should run for reelection, nearly as many as the 58% who said that in October. But among those under age 45, only 23% say he should run for reelection.
