I remember reading that about 67% of respondents said in a poll in the late 1960s that they would vote for a qualified African American to the Presidency. Could such a man have been nominated and elected pre 1980?
67% no longer considered it to be a factor in voting for a presidential cadidate.
So really, said black canddiate would have to win somewhere in the neighborhood of 70%-80% of those 67%. A pretty dang heavy task to say the least.
Really doubtful either party could've done it. If Black Republican ran the white Democratic vote of the time would show up in large numbers in opposition of what they would consider a continuation of "benign neglect" aimed at forcing them to integrate with blacks. If a Black Democrat the likely white Republican would portray him (or her if Shirley Chisholm runs) as a "radical liberal" on the the lines of George McGovern. And they would likely lose on the same level.
Due to the fears of white privileged America, neither of these have a chance. Black Republican would at least win a few feel good WASP states, because he scares them the least, but comes nowhere near the 270 EV mark.
This is probably the only post I'll ever make that Oldiesfreak likes.
