I'm no expert and I could be completely off base here, but just how orthodox are Jews anymore? Just how much attention do they really pay to what's going on in Israel, Lebanon, Syria, Gaza, and the West Bank?
I suspect that many Jews today suffer from the same problems that Christians do - they're buried in their iPods, X-boxes, computer dating, and similar it's-all-about-me-and-what-I-want.
These folks haven't done the research to unearth just how much of an anti-Semite that Obama is.
It's just another example of how the MSM is much more powerful than even we realize.
