Did Reagan pick Bush St as his VP or not? And eventually his successor? Even at the primaries, Bush was considered from the moderate to liberal wing of the party. I’m not going to argue further with you since it’s waste of time. Simply pointing out that if we look at the fact Reagan was capable to endorse someone who you wouldn’t endorse.
Do you honestly believe Ronald Reagan would’ve endorsed a Socialist like Willard and actively campaigned for him ? If you do, then you never knew Reagan. He would be disgusted at charlatans like him. These are the people he fought against his entire political career.
