Shirley did confirm what you said, that Reagan came to respect Bush as a loyal ally while he was VP.
I agree with you on how Reagan would view Palin.
I though Bush’s reactions to Gordon Humphey’s last ditch plea to include the others, “I’ve worked all my life for this and I’m not giving it up.” sounds eerily like something Mittens would say. These Eastern snobs think the Presidency belongs to them not to the hoi polloi:
“When Bush came out of his holding room and headed to the stage, Humphrey pleaded one last time to include the others in the name of party unity. Bush spat back at Humphrey, whom he loathed, No fing way! Ive worked all my life for this and Im not giving it up. . . . Ive done more for party unity than youll ever know!”
