Yes they did.
Once again the Bush wing of the Republican party went after Reagan hard, and would not endorse him unless he took George as his VP. That’s historic fact.
I like the Reagan Wing of the Republicans. I cannot STAND the Bush wing. They are DNC with Rs by their names to keep conservatives in check.
Reagan win twice in landslides with greater than 94% of Republicans voting for him. To say the Party hated him is simply bs. A small elitist element hated him.
