If you look hard enough, you can see that Hillary Clinton’s adoring fans were booing Barack Obama during her farewell address. I frankly couldn’t pick it up on the TV coverage, but apparently it was embarrassingly noticeable to those there. This tells us a few things.

First, the we’re-mad-as-hell-and-we’re-not-voting-for-him phenomenon is not entirely a Republican pipe dream. The boo birds may eventually come around, but some of them sound awfully upset. Second, Hillary can’t deliver these people. Her mere presence is a reminder that Obama did her wrong. If anything, she may spur the sense that in four short years (two actually, because that’s when the next primary season will begin) she could be on the trail once again if Obama would just go away. Her talk about her noble crusade and never giving up hope may be counterproductive to the entire effort to get them on the Obama Express. Finally, people are not entirely rational. They cut off their noses to spite their faces all the time, and they let bitterness get the best of themselves. Telling them to stop being irrational doesn’t usually work.

Obama should be forewarned: in order to get the Hillary faithful to vote for him (not to mention volunteer or give money), he first has to get them to stop booing.
