Please give examples of Tweets so repellant as to turn the election in such a dramatic manner.
There had to have been dozens.
I'll give you one. And I recall people around me talking about it and it was amplified by the press right before the 2018 midterms and arguably led to GOP losses that year
When a judge tossed out Stormy Daniels lawsuit, Trump tweeted how now he can go after "horseface." Which then drew a response from her of something to the effect of "bring it on, tiny."
This need to tweet and respond to every slight was a big part of his drama. I once said that if Trump loses 2020, it'll be of his own doing. This is not a defense of the press who also conducted themselves horribly during the Trump era. But Trump became his own worse enemy and did give them ammo
I understand some consider that "fighting." But that conduct from a president I would argue turned off many people
