Overall, 38% of likely voters think Biden has some form of dementia, while 48% disagree, and 14% say they are not sure.
Sixty-six percent of likely Republican voters believe Biden is suffering from dementia, and 61% of all voters believe it is important for the Democratic presidential frontrunner to address the dementia issue publicly.
The poll also found:
