Most polls seem to show both Moslem and Jewish support for GWB at 20% or so, nationwide. Unless there's lots more harassment of Moslems going on lately, I would think that they would be much better off supporting Bush. (Similarly for the Jewish voters.) Most Jewish (and other "minority") voters though tell me that it's the party not the policy that they dislike.
All politics is personal. When someone says something like "xx% of Jews (or Moslems or Hispanics or Blacks or YFEGs) are stupid" or "should be expelled" etc., those associated with the expressor tend to be seen similarly. This has been true in politics for (in my observation) over 50 years. I'm sure it goes back.
My comment that more Jews would support GWB than Muslims was based on the following from the lead to the thread: "Nearly 68% of US Muslims said they would vote for Democrat presidential hopeful John Kerry in the presidential elections, against only 7% eager to vote for the incumbent Bush."
