"Amazing how the septuagenarians and octogenarians in the Democrat party are willing to break faith on a decades-long commitment to the security of Israel because a bunch of know-nothing college kids and chuckleheaded academics have joined with a small foreign contingent in the party -- many of whom can't even vote -- to mau-mau them into obedience."
My understanding is the larger factor is the substantial arab/muslim vote in Michigan, Minnesota, and New Jersey.
