There's an interesting lecture you can get online for free from www.fee.org which goes through each of the stupid things Hoover and Roosevelt did. Roosevelt really didn't know anything about economics. He really didn't seem to have a guiding economic policy vision either. He seemed to want to just get votes. At one time, he was presented with 2 drafts for a speech. One advocated cutting taxes. The other advocated raising taxes. Roosevelt told his speechwriters to mix the two speeches into 1.
I saw parts of the show and thought it was pretty even handed. They made no apologies for Roosevelt failing to act when it came to civil rights and an end to racism in the south. It was Eleanor who pushed for reform but Franklin knew it would cost the Dems the southern vote so he would not even support a federal anti lynching bill. This is shameful. I suspect if someone like Warren Harding or Calvin Coolidge were president at that time, they would have supported this legislation.
A black historian on the show said FDR was not a great president because he took no strong action on this issue. He said a great president is one who takes bold, decisive action even at the risk of losing political capital. Sounds to me like a decription of GWB.
