How as someone who will vote for him do you expect Trump to “deal with the left“ upon reelection? Is there anything that he can do or fail to do that will disappoint you?
He’s just a man, subject to the constitutional constraints that apply to all presidents.
It is one step at a time. Trump is President, then we can work on getting Democrats out of office one seat at a time, right down to dog catcher.
Then, if necessary, keep working to remove their power permanently.
