In Biden’s case, the criterion is he’s not Trump. Otherwise, he’s a shitheel politician, always has been. He does like to tout his bonafides though. It would be a good story if there weren’t decades of evidence of his suckalige. If it weren’t for Obama’s popularity and Trump’s ineptitude, no one would give Biden the time of day. He appeals to virtually no one, which is why he has to buy votes and “no true Scotsman” black people.
