It's an article of faith on the right that Barack Obama has irreversibly alienated Jewish voters by
Obama also has wreaked havoc in the the Democratic Party.... He's alienated Jewish voters.
"He's alienated Jewish voters"! Period! All of them, presumably!
Has he? Let's go to the Gallup videotape:
Mormon registered voters overwhelmingly support the candidacy of the first major-party presidential candidate of the Mormon faith, with 84% saying they would vote for Mitt Romney, compared with 13% who prefer Barack Obama. Obama, meanwhile, enjoys solid support from Jewish voters, 64% to 29%.

So he's supported by only twice as many Jews as Romney! See, it's true! Jews hate the dirty Democratic anti-Semite!
Now, admittedly, this is a merely overwhelming margin in Obama's favor. In 2008, according to the exit polls his margin among Jewish voters was mind-boggling -- Obama 78%, McCain 21%.
So Obama's lost 14 percentage points. That's gonna hurt, right? Well, let's do the math. Jews make up 2% of the electorate. 14% of 2% is ... um, a little than three-tenths of 1% of the vote.
Wow! Three-tenths of 1%! How can Obama possibly survive that loss?
