Krauthammer was a democrat then, for Jimmy Carter. I guarantee you that Mitt Romney was either for Anderson or Bush. Just about all the Senators were for Bush, except a few, like Jesse Helms. I worked for a Republican Senator who was very anxious to not have to do what Reagan said. He would definitely have been a Bushie.
Who did Cochran endorse?
Willard never supported Reagan or Bush, he said as much. He likely voted Carter, Mondale & Dukakis.
