I do not think Trump is an ideologue. I think he showed up at the White House, ready to make deals with Democrats. But they declared war on him, so he has no choice but to go to his base.
The other poster said republicans won in 2016 because they went hard right. That is hilarious since Trump was accused of being NOT conservative in thousands of posts on FR. My post was in response to his/her comment. I agree with you that Trump was never an ideologue. He is a America first pragmatist.
