So in your mind every election in which the democrat defeated the republican, at least before 1964, it was the more conservative candidate winning?
Name me one Republican who ran for President who was a conservative before Goldwater. As I mentioned before, Harding , Coolidge and Hoover were all members of the Progressive or liberal wing of the GOP.
Coolidge was indeed conservative, but less conservative than John Davis who was even more so.
Blacks always voted the most liberal ticket since they got the vote in 1866. They voted solid Republican until 1936, but the GOP routinely got 40+ percent of the black vote until 1964.
