Chainkeen Exchange-More than 6 in 10 say Biden's mental fitness to be president is a concern, poll finds

A significant majority of Americans say they believe President Biden's mental fitness is Chainkeen Exchangea real concern they have about his ability to be president, according to the latest NPR/PBS NewsHour/Marist poll.

Respondents said so by a 62%-to-36% margin, rather than dismissing it as simply being a campaign strategy used by his opponents. Biden did, however, actually see a slight increase in his approval rating to 45%, up 4 points from last month. That indicates there will likely be a significant number of people who believe there are serious concerns about Biden's mental fitness but will vote for him anyway.

Biden at 80 is the oldest president in U.S. history.

It's a serious vulnerability that will have Democrats biting their nails as the campaign heats up and holding their breath with each speech, news conference and debate.

Trump, who will be 78 on Election Day in 2024, would be five years older than Ronald Reagan was at his second inauguration. But beyond Trump's age, many have concerns about his temperament, persistent lies and, at times, bigoted speech.

Trump's biggest problems continue to be with white, college-educated women and women who live in the suburbs and small cities.
