Why they wouldn’t want him would have nothing to do with sex.
I see your point and agree.
The thing that bothers me is the assumption the person would be “frozen in time” and thrust forward X amount of years and would magically be in the opposition. I have little doubt if most of these people were around today, they would’ve “evolved” (or devolved) with the party.
There’s a former Governor of Alabama, John Patterson, nearly 100 years old, he ran against George Wallace in 1958, painting Wallace as a left-wing integrationist radical (the infamous contest where Wallace disavowed his racially moderate agenda and screamed he’d never be “outniggered” again and would be 100% rock-hard on segregation from then on). Patterson was close with the Kennedys (unlike Wallace), even as the KKK-supported candidate. Flash forward 50 years to 2008 and Patterson heartily supported Zero for President as a “loyal Democrat.”
