I fail to see how being a Republican obligates me in any way shape or form to support Trump. As Trump himself said in an interview this week, quoted in this morning's WSJ:
This election isn't about the Republican Party, it's about me . . . I'd rather have a unified Republican party, but I'm not sure that's as necessary to the voters, to see people getting along. They are voting for a person, not a party.
That says it all, IMO. The GOP is merely a vessel for Trump's personal, third party campaign. He demands, and expects, no more loyalty from Republicans (or conservatives) than Pat Paulson did.
The conservative movement and Trump have nothing in common, and little to gain in pretending they are allies. Trump's is a transient cult of personality, which will leave little in the way of a footprint after its Dear Leader is done and gone.
