I'm going to personally say Pete is scummier. Bloomberg just seems like a rich, narcissistic racist who thinks he can buy an election. If he can't, oh well, he's just go swim in his money vault. Pete seems to want to actively destroy the party and kneecap whoever wins the nomination, likely Bernie, on his way out. He's now suggesting voter fraud in Nevada when he just lost hard. At least Bloomberg hasn't stooped that low...so far. Either way, both of these guys make Biden look better by comparison. He's bad, just not that bad.
