A significant majority of Americans say they believe President Biden's mental fitness is a 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.
