To be fair I support many of the policy decisions he's done. Here's the thing....since virtually everything Obama did was quasi-unconstitutional/anti-American, all Trump had to do was the opposite of what Obama did to do the right thing. And so far Trump has not tried to implement his screwball ideas about trade and the deficit.
The problem is: what about the future? We are not just trying to win battles now, we have to win the future. Since many Republicans have decided to junk conservatism and that populism is now the way to go, how do we persuade future voters to vote for the right things?
Because Trump has no conservative ideological moorings (even Limbaugh and Hannity admit this), we do not know what he'll do in the future. We do know that he's absolutely not any kind of a salesman for conservatism like Reagan was. It's all about what appears to be "winning" at the moment.
