The Jews voted for Roosevelt by 90% in 1940, and 90% in 1944, they loved the guy.
For a shocking look at FDR's disregard of Jews, I recommend THIS PROGRAM. I don't see how a Jew could ever vote 'rat after FDR didn't lift a finger to help them. FDR also opposed an anti-lynching law that had broad bipartisan support. Was he a snooty Hyde Park racist?
