Comments for that post aren't working, and I don't seem to be able to fix it. So, if you want to comment, you can do so here.
UPDATE: The short version of my previous post is, Bush got around 25% of the Jewish vote in 2004. There are reasons to believe that McCain will be more popular among Jews than was Bush, and that Obama will be less popular than was Kerry. Therefore, one can expect McCain to do better than Bush among Jewish voters. Please read the prior post for details before commenting.
