Many Americans say they do not want President Biden to run for re-election, and his age is a big reason.
In an NBC News poll released last weekend, 70 percent of adults said Mr. Biden, who is 80, should not run again.
Mr. Biden, already the oldest president in U.S. history, would be 86 at the end of his second term.
Mr. Biden’s age is a frequent punchline on late-night television.
With the obvious caveat that a serious age-related gaffe or health crisis could change things, there are good reasons to think that Biden’s age may matter less than some polls suggest.
