Unfortunately, the one I’d most like to change is outside your parameters: 1964. A Goldwater win makes us an entirely different (an din most ways, better) country today.
I was thinking along the same lines but even before 64. I’d like to have seen Nixon win in 1960, hopefully keeping us out of Vietnam, and then the radicalization we saw in the 60’s and early 70’s might not have been so great.
This is what has really destroyed this country, the radical break from traditional values and work ethics largely attributable to the 1960’s. I honestly don’t know if we’ll ever recover.
Without the Vietnam war to rally around though the radicalization may not have gained as much traction as it did. Who knows though. We’re stuck in this reality I guess.
We have a winner.
Definitely Goldwater, 1964.
