I think it's clear that around 25% of America's Jews would vote Republican, no matter what--they may harp on Israel as their reason--but even if Israel was off the table, they would vote Republican. I'm guessing 5% were swayed by the Republicans-are-better-for-Israel mindset. Israelis should not be surprised that the overwhelming majority of American Jews vote Democrat. Israelis don't like American Jews. What they have a hard time understanding is that a large core of American Jews hold equally negative views of them. That's because Israelis, like Republicans who watch only Fox News, live inside of a bubble in which they go to GA conferences, hear about Jewish Federation love fests and think that so many American Jews adore them. They don't. Worse still: that Israel's Prime Minister interceded in the US election on behalf of Mitt Romney and that he has ingratiated himself to Congressional Republicans, has only turned off a large number of younger Jewish voters. Israel is making it, in the long run, a lot harder for itself in America.
