In advance I realize that the idea presented here might be slightly ASB, or even generally foolish, but I'm considering the following sequence of events.
Watergate happens, Nixon doesn't resign and is instead impeached. Nixon goes to trial in the Senate, and only very barely avoids conviction/removal.
I'm wondering what, if any POD could make such a sequence of events possible.
And beyond the plausibility issue, I'm wondering what the rest of Nixon's Presidency looks like. I predict that Nixon will be the absolute lamest of lame ducks, but other than that I'm not entirely sure.
Again I apologize if the idea is laughably unlikely.
