The findings in the pivotal states of Arizona, Florida, Michigan, North Carolina, Pennsylvania and Wisconsin were released Thursday amid a sustained push by the Trump campaign to portray Biden as incapable of handling the demands of office. Most respondents in those states, which will play a huge role in determining the presidential election winner, do not have confidence in Trump’s ability to take on the job, either.

A 51% majority said Trump is mentally unfit to be president, while 49% answered that he is fit to hold the job. A similar share, by a 52% to 48% margin, responded that Biden is mentally unfit to be president.

Voters had more confidence in the presidential hopefuls’ physical fitness to hold the White House. A 52% majority said the 74-year-old Trump is physically fit to be president, and 54% said the same about Biden, who is 77.
