1984 was because we had an incumbent conservative president and the RINO wing had no choice but to go along.
1964 and 1980 was because the conservative wing got united behind a single candidate early and was able to force the RINO wing into a background role. They did so in 1980 because Reagan chose a RINO for the VP slot. They refused to do so in 1964 and helped re-elect LBJ. There's a lesson here.
Yeah but the gop party hacks are all making great money and don’t care to rock the boat.
