Romney knows that, in the conflict between Israelis and Palestinians, Americans’ sympathies are overwhelmingly with Israel. This is a freebie. You want to talk about the last acceptable prejudice? This is a serious contender.
His policies notwithstanding, George W. Bush personally shied away from overt racism toward blacks, Hispanics, and Muslims. Romney, by contrast, will eagerly exploit bigotry when he thinks he can get away with it. In this case, he knows he can not only get away with it but benefit from it, because so many Americans will cheer the dog whistle and so few will be outraged. He showed in prep school that he won’t refrain from hate if hatred has no negative consequences.
