Bachmann voted and I think worked for Carter’s campaign.
Reagan was an enrolled democrat until 1962. He was a union leader prior to entering politics. He must be a RINO.
Michelle Bachmann grew up in a Democrat family and campaigned for Carter. She, too, must be a RINO.
And don't forget Sarah Palin. While governor she supported a 25% profits tax on "big oil." What could be more RINO than that?
Reagan cast his first presidential vote in 1932 for Franklin Roosevelt, and did so again in the succeeding three presidential contests. His faith in FDR remained undimmed even after World War II, when he called himself a New Dealer to the core.
