Unfit maybe. But mentally unfit? I don’t think any candidate from either party for the last dozen elections has had thirty percent of their own party think that. Quayle is probably the closest, and he was VP.
I don’t think anybody thought Obama was mentally not up to the job, except maybe the “Bell Curve” racists. They may have felt him unqualified because of lack of experience, but not mentally incapable.
Think of G.W. Bush. He was a bit of a lightweight, his own party supported him strongly.
WT Holy F? You think Obama or GHW Bush or B. Clinton or Reagan were considered mentally unfit by a quarter of their own party members? How does a candidate thought that badly of get the party nomination in the first place? Being incumbent isn’t an explanation because you have to get elected the first time.
Hell, Carter wasn’t thought highly of, but he wasn’t thought mentally deficient.
As stated, even Reagan wasn’t showing any signs of decline in his second election.
I would think, purely on speculation, that number would be lower than 10%. Maybe if you take the electorate as a whole, but then you have to include low information voters who probably only barely know the names of both candidates.
If you’re including non-serious answers to polls, then sure, 10% is possible. That’s in the range of people who would say the moon landings didn’t happen, or bigfoot is roaming the woods.
YES! Colbert hit that message last night, but comedians aren’t the same as news anchors.
