As President Biden prepares for an expected re-election bid, Democratic leaders are increasingly enthusiastic about his candidacy. Many of his party’s voters aren’t on board.

Concerns about Mr. Biden’s age and abilities are front of mind for some Democrats, even those who think the 80-year-old president has done well during his first two years in office, according to recent polling and Wall Street Journal interviews with more than two dozen people around the country who voted for Mr. Biden in 2020.

“I think he’s too old,” said Kelly Spencer, 35, of Flatonia, Texas, a Democrat who voted for Mr. Biden in 2020. “And maybe that’s a little ageist on my part, but I think he’s too old. I worry about cognitive decline. I worry about a stroke, anything like that.”

[And well they should. Nothing over the last two years has dispelled worries about Biden’s cognition or energy. His increasing reliance on yelling speeches seems to be a strategy to answer doubts about the latter, but angry bursts of yelling might actually cause more curiosity about cognitive decline as a tradeoff. — Ed]
