You left out Buchanan. He blew the Pubbies up in 1992 before Perot ever got a chance. With his sour face and angry diatribes, he became the poster boy for liberal fundraising. Bush I wasn’t perfect, but Buchanan did serious damage to the Republicans before leaving and then totally destroyed Perot’s Reform party, which actually had some momentum going to be a viable third party before Buchanan got there.
it’s people like Buchanan and Huckabee that excite people into writing big checks for Planned Parenthood and NARAL
Yep. A primary challenger from his party's base (e.g. Buchanan for Bush 41, Kennedy for Carter) for an incumbent President is very bad news, almost always resulting in a loss.
