Republicans abandoning Trump?

[treee]

This is the general gist: Most Republicans already in office and a large portion of the electorate didn't want Trump in general in the first place. Once his populist message really started picking up steam with primary voters, they started taking him more seriously. When he won the nomination, most Republicans fell in line and supported him if only to prevent a more progressive agenda. Now that he has become so outlandish, Trumps loosely held conservative principles do not outweigh being associated with a person viewed so horribly by the general populace.
