Reagan was hated by establishment Republicans, and of course by all Democrats, from the beginning. He was that generation's Sarah Palin (if she had stayed in).
The establishment Republicans sent in GWH Bush as both a CIA Handler (He was formerly the head of the CIA) and to keep Reagan in check.
I remember him as one of the most visible VP's in my memory, GWH was.
The Establishment forced Reagan to take him.
Who? Do you mean GHW (as in Bush 1)?
