This graph is depressing, though. I can understand preferring Obama because you think Hillary’s easier to beat — I’m of the same opinion, albeit less convinced with each passing day — but preferring him because you’re more worried about a Clinton presidency than an Obama one? Anyone willing/able to explain that? He’s the more principled leftist, as near as we can tell; he’s certainly more dovish than she is. Is this just calcified Clinton hatred among Republicans manifesting itself (i.e. anyone but Hillary) or has the Prince of Peace actually sold them on his “post-partisan, so long as I get to continue to vote liberal” shtick?
