Reagan also admitted that he voted for FDR and repented for it. Let me know when Perry repents for voting for Jimmy Carter, Walter Mondale, and Michael Dukakis.
You know, I am reading the Reagan Diaries, and while he talks about voting for FDR 4 times, I cannot find anywhere where he says it was a mistake, or "repents" as you put it. In fact, in at least one entry, he make is clear that it was never his goal to undo the New Deal (the Great Society was a different story).
