With national hero Ike on the ticket and with five terms of Democratic rule, yeah, Dewey would win. However, Conservatives wouldn't even have Richard Nixon to balance the ticket, and there wouldn't be as much motivation by Republicans, but still a lot.
That leads me to something I don't get...
Richard Nixon was, for most of his public life, even while President, considered a Conservative. Liberals in his time hated him, and he hated them. Why is he now considered a Liberal, and even a Communist, by the right?
