Senator Claire McCaskill endorses Barack Obama. Hillary Clinton still obviously has the overall endorsements leader, as the establishment candidate is bound to, but the recent high-profile endorsements have all tilted Obama’s way. I have to say that I don’t totally understand why that is. You would have thought this would have come after Iowa as people try to jump on the apparently victorious bandwagon. It’s true that Obama’s odds look better than they did in, say, November but I think you’d have to say that Clinton is the favorite to win so Obama’s endorses are taking risks and politicians aren’t normally big risk takers.
