Any thoughts on how a 4-way 1968 would go?
Say Reagan takes the nomination at the convention, in part due to Sen. Thurmond's support and the southern bloc. Rockefeller, defeated again by a conservative ideologue, is fed up and runs as an independent, maybe with Romney as his running mate.
It is a safe assumption that Humphrey is still going to take the Democratic nomination a couple weeks later.
How would it turn out?
