I am not talking about what I think he should do. I am talking about what he claimed when he was running and what his supporters claimed.
Well I can only speak for myself, I never believed any politician cared about voters or conservatism, but many did. I also believed that every politician in DC would try to get rid of him. Election night, many stated that having the House and Senate would be a windfall of conservative legislation despite Trumps (supposed) conservatism. The opposite happened, both House and Senate had no interest in passing any conservative legislation.
So Trump had a choice, be a purist with no flexibility and get nothing done or push for collaboration.
The problem isnt Trumps purity, it is the GOP. Trump never claimed that he could force the GOP to be conservative. He, like most, assumed they were.
I would hope that one would reserve judgement if they havent formulated what can be done that isnt being done. Remember that most of the GOP did not vote for Trump. That says it all and creates an impossible working environment.
