What does Trump not a Conservative even mean? Trump adopted all the policies Conservatives support
By that the speaker means "I'm sticking to the established vetting process that has given us every loser since the Reagan era ended."
It's KristolSpeak for 'Voters? Hmph. I'll decide who the candidate will be!'
Conservatives so not support "expedited return of illegals" (to quote Trump), large tariffs on imported goods, increased taxes, "renegotiating" the Paris Climate Accord, etc.
Conservatives have principles. The two most important being
Rule of law
Respect for private property
Trump is terrible on both. He supports Kelo, which shows he has scant respect for property rights. He is completely tone deaf with respect to principle of rule of law. He is completely unprincipled. His "arguments" never even rise to the level of casuistry. The principle of rule of law does not guarantee that I always get my way.
But I agree with Mr. Schlicter, Hillary is unimaginably worse.
