A majority (55%) of likely voters surveyed thought it was more likely (much more and somewhat more likely combined) that Vice President Biden is in the early stages of dementia, while 45% thought it was less likely (much less and somewhat less likely combined). Overall, subgroups who normally approve of Trump's job as president, were the most likely to believe Biden could be suffering from dementia. Thus, majorities of Republicans (77% more likely/23% less likely) and Independents (56% more likely/44% less likely) thought Joe Biden had early-onset dementia; while nearly a third of Democrats (32% more likely/68% less likely) thought this was the case
