Judging by Nixon's approval ratings around Watergate, I'd say that McGovern takes all fifty states.
Exactly. Nixon got down to a 19 percent approval rating I believe in the last Gallup poll before his resignation.
I'd vote for McGovern, and he would've won. I can't imagine anything McGovern could or would possibly have done that would've been as bad as Watergate.
I'm assuming that with hindsight does not refer to right after Nixon resigned. Obviously Nixon would have won then. But say, 20 years later, if all the people in 1972 voted again, I think McGovern would not have won by as much.
