In the spring of 1980, the race for the Republican presidential nomination got nasty. The front-runner, Ronald Reagan, said his main challenger,George H.W. Bush, wasn't a real conservative. Bush went on the attack, accusing Reagan of peddling "voodoo economics" and "a list of phony promises."
Four months later, Bush was Reagan's choice to run as vice president. He denied using the words "voodoo economics" -- or at least he did until NBC News found a videotape of the speech. Nevertheless, Bush served for eight years at Reagan's side and won his boss' endorsement when he ran in his own right in 1988.
