The Zogby Poll®: A majority of voters believe Biden is in the early stages of dementia; 60% of younger voters think so; Swing voters less likely to think Biden has dementia

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

At the same time, some important subgroups did not believe the vice president was exhibiting a declining mental capacity. While a majority of men (60% more likely/40% less likely) thought it this was likely, women (50% more likely/50% less likely) were less likely to think that the vice president was in the early stages of dementia.

There was also an inverse relationship in the data between age and the likelihood of voters believing Biden had early-onset dementia, for example; as the age of voters increased the likelihood of voters believing Biden was exhibiting early-onset dementia decreased.

Younger voters aged 18-24 (60% more likely/40% less likely) and 18-29 (59% more likely/41% less likely) were more likely to believe Biden had dementia than older voters aged 65+ (50% more likely/50% less likely).
