My favorite response: "I think anyone that looks rationally at these poll results would have to conclude that Obama voters are incredibly poorly informed about major issues that occurred during the campaign -- my guess is because McCain voters got their information from different types of media than Obama voters did."
He admits he only polled Obama supporters, yet from this he magically infers that McCain voters are better informed and speculates that this is because their sources of information are more reliable. Clearly, this is a fine mind at work.
