I'm gonna make a few points on FDR and Reagan. First off, M is compeltely right that the percentage of EVs is the thing to look at, anything else is ridiculous. That's like saying that Nader is much more popular than Washington was, b/c Nader recieved more popular votes. And the highest EV-percentage since pre-civil war era IS FDR, in 1936.
One of the left-wingers in these times were Ronald Reagan, btw, who supported freedom of speech for Communists, one of the things that makes him great in my opinion. Just a little reminder, PD. There was not thousands of spies everywhere, I thought McCarthy was well buried, but I guess I was wrong.
To RP: I am pretty sure that Churchill did what he could to fight Stalin, but was betrayed by FDR and Britan was too weak to go on it's own. FDR and Eisenhower, like most Americans of that time, failed to see the Communist threat in time, which put much of Eastern Europe into Soviet hands.
There were a lot of spies and communist sympathisers in the FDR administration. Alger Hiss and Henry Wallace to name a couple (Wallace wasn't a spy, but he was a sympathiser. What you said about Reagan is true, he always supported freedom of speech, just not subversive communism. BIG difference.
Also, you were right about FDR and Churchill except I would say that FDR was more compliant with Soviet demands than what you can attribute to nievity about the Soviets. I think that FDR let the entire world down when he AT LEAST failed to stop Soviet control of Eastern Europe. Patton had the right idea. We should have kicked the Soviets butts back into Russia, where they belonged.
