It’s pretty to easy to understand if you think about it. If you are a Republican politician, you have your core that will always vote Republican no matter what.
Trump added significantly to the people who will vote Republican, that do not normally vote.
So, if you are a Republican politician, you need both voting populations if you want to win your election.
That is the main reason you see so many Republicans embracing Trump’s beliefs and fans.
It will not stop until you have your hardcore Republicans who always vote Republican say, “We reject Trump, wtf are you Republican politicians doing?”
As you can see by most of the Republicans on this board, that will not happen anytime soon.
And I don’t mean just saying it, say it at the polls by voting against Republicans. You can say Trump sucks, but if in the next election it’s Biden vs Trump and you vote 3rd party, not Biden, you are still supporting Trump.
