People, people. Those comments (all of which are objectively correct) are not predictions. Unless the slump somehow ends, then an upset will always be at least possible. Plenty of laughably bad candidates have gone on to win elections.

So not impossible. Though seemingly unlikely.
And which of the things in your OP fit the 1976 Jimmy Carter? He certainly wasn't a fraud (quite the opposite in fact), or a failure. Definitely not a nutter or a creep. And isn't virtually every career politician a hack to an extent? Oh, and obviously not the other three things either.
