If you watch the clip itself, it’s not clear at all what Obama’s supporters are supposed to want revenge for. Obama mentions Romney name in the context of his run for the senate in Massachusetts — back when Romney was quite the moderate — and the audience starts to boo. Obama says “no, no. Don’t boo. Vote. Vote. Voting is the best revenge.” Revenge for what? Him running for the senate? Revenge for Romney daring to challenge Obama? I understand Obama is bitter. That’s been obvious for a while. But it’s just a weird and narcissistic assumption that his supporters want “revenge” too. Doesn’t mean it’s wrong, though. Which makes the whole thing even creepier.
