Tom Woods taught this great on-line course: FDR and the New Deal. Hope he offers it again. He also brought in Robert Higgs's "regime uncertainty", which is so obvious these days (businesses won't start up, expand or hire because they're afraid what the presidential administration is going to do next to pull the rug out from under them). You can get some good info on the depression at mises.org.
When liberals ask me what I think of Obama, I tell them that it's a shame he said he wanted to use FDR as an example for fighting the current economic woes...play up that he's not a bad guy, but chose the wrong role model. It diffuses any any angry rhetoric they want to vent and sometimes actually allows for a serious discussion.
A lot of older Americans don't even know all the garbage FDR did: trying to expand the Supreme Court so he could stack it with all his cronies, etc. And some say the reason he won the first election was that he promised to repeal Prohibition. Interesting.
