He was a favorite in the 1988 presidential primary because he was such a a great public speaker…
He got over his stutter when he was a child, and a stutter doesn’t make someone say something completely different than what they meant to. Hell, he wasn’t even doing it while Obama’s VP, and he was in his 70s then.
Stop pretending he just has a stutter, he’s 80 years old and he gets confused sometimes. It’ll happen to all of us if we’re lucky to live that long.
That doesn’t mean he’s still fit to be presidet, and he sure as shit isn’t the best option for a Dem candidate even if he is mentally fit for office.
