Serwer finds a new attack ad against "West Virgina Democratic Congressman Nick Rahall for having chaired Arab-Americans for Obama during the 2008 election":
Rahall is a Christian, but I think it's fair to say that most people that would react negatively to someone chairing a group called Arab-Americans for Obama don't really make a distinction between Arabs and Muslims.
Again, the underlying point here is that an entire group of people is not just outside the bounds of American legal protections, but simply shouldn't be allowed to participate in something as fundamental as the American political process.
