I think you're understating how much of the American right dislikes Trump. Actual conservatives supported Cruz and Rubio (both of whom have been very consistently critical of Trump's shenanigans). Ben Sasse and Rand Paul are also very vocal.

In print, National Review, The Federalist, Commentary, and similar news organizations have been against Trump since the Republican primary, not in small part to his playing footsie with racists.
