The main point of evidence for the largely spurious Republican claim that Jewish donors are abandoning Barack Obama is alleged non-support by entertainment mogul Haim Saban. It was a weak claim to begin with, as Saban didn't support Obama in 2008 either -- there's no evidence that former Obama backers are now turning on him due to his positions on Israel.
But it turns out that even Saban himself is pushing back on the idea that Obama is hostile to Israel, and is arguing that Obama's words are being distorted by Republicans with a partisan agenda (an agenda which Saban does not seem optimistic will be successful). He also noted that he had no substantive problem with Obama's speech (though he had some concerns with respect to form), and that he would be pleased to donate the maximum allowable amount to the Obama campaign if asked in 2012.
We can only hope all Jews are this "anti-Obama" in 2012.
