They are; the party loyals use softer language (like John McCain), but there are plenty who owe trump nothing and are a bit louder (like the Koch Brothers)

We'll see how much the Koch brothers care in the mid-terms; if they're not pressuring senators and congressmen to oppose trump at the risk of primary challenges, we'll see that either their loudness is only about his tone, or that they are powerless to fight Trump's base.

There are like two dozen actual "conservative" true believers in America, and most of them (Bill Kristol, David Frum, etc) hold some pretty odious views about things like war and torture.
