Read Ronald Reagan’s autobiography An American Life. You’ll learn that RobbyS is right. Reagan did admire FDR, as hard as that may be to understand. You’ll need to know his upbringing and the times he lived in to know from where he is coming.
I never disputed the idea that Reagan may have admired FDR. Most Americans of Reagan's era did. What I found incredible, is that "he was a life-long admirer of FDR."
I also find it hard to believe that he was a New Dealer, as RobbyS claims. He needs to cite a source for that claim, or retract it.
