Wouldn’t go over well, but if it was a Republican that the evangelicals liked plenty of them would let it go with “we are all sinners.” That’s what an acquaintance of mine said to me two days ago about Trump. I have to roll my eyes a little, because I feel absolutely sure she would be a full on hypocrite if it was a President who she didn’t agree with on policy.
It’s the post me too movement. The difference in power would upset a lot of people, especially a lot of women. Already plenty of people had a problem with it when Clinton did it. It doesn’t sound like Monica was forced in any way though.
An affair with someone outside of the White House, especially if they are closer in age to the president, would be ignored by most.
