In an unusual break from rubbing shoulders with the rich and liberal at party fundraisers, Obama spoke at a campaign rally in western Maryland for the state’s lieutenant governor who’s gunning for the top seat in November.

But his audience left their own seats in droves – while the president was still speaking.

The most amazing part of the rejection at was the crowd’s makeup — overwhelmingly black – and Obama’s subject: encouraging heavy minority turnout for the midterm elections.

Here’s how Politico reported it:

This is Obama country — Barack Obama Elementary School is just down the road, and close to 90 percent of votes cast here in the 2012 presidential election were for him, the best he did in any county in the state. The crowd was energetic in waiting for the president and in welcoming him to the stage, but once the president started speaking, the crowd began streaming out, a few at first, but then by the dozen once Obama was about 10 minutes into his talk.

Considering the speech lasted 25 minutes, they didn’t even make it to half time.

So huge numbers of black Democrats in an area so besotted with Barack Obama that they voted in near-unanimity for his re-election — even named an elementary school after him for God’s sake — decided to try to beat the traffic before the president had finished the throat-clearing part of one of his insipid speeches.

That wasn’t the kind of voter turnout the president was looking for, but “let me be clear” doesn’t come close to describing how perfect a picture it is.
