I searched for a thread like this, but I couldn't really find one.
In 1968, Richard Nixon had Spiro Agnew run with him as his Vice Presidential candidate. The short hand reasons I've heard why he was picked are that he was a Southerner which helped votes in the South, that he was uncontroversial and inoffensive and thus didn't offend the people Nixon wanted to please, and that it had been shown that when any prospective VP nominees were attached to Nixon his prospective polling numbers went down, so Agnew was the closest thing to running with no one that Nixon could get.
My question is, who besides Agnew could have been a possibility to be Nixon's running mate? I don't mean names that were just touted around, as those are always many. I mean people who, for the time and place and circumstances, and with Nixon's character, might have been truly feasible (whether their names were touted around or not).
