Remember when Bill Kristol predicted that Trump’s support would collapse because he declared that he would protect Social Security and Medicare? Surprise: there are virtually no sincere small-government types out there in the real world. Wealthy donors want tax cuts.... But people who actually care about the government spending too much in general (as opposed to spending too much on Those People)? No such constituency.
There are just not that many of us around who want real cuts--deep and across the board.
