A Pit Bull Perhaps?

From Would You Believe ...? by Josh Marshall:

One of the advantages of running a presidential campaign is that roughly half the country is deeply committed to believing or at least saying that virtually anything you do or say makes sense. And so it is here. But, look, if you were living in the real world, if you were some hotshot young executive at a Fortune 500 company trying to rise in the ranks, and you pulled some whacked crap like this, it would probably get you blackballed permanently. People would think you were either deeply unreliable or maybe just had a screw loose. And yet here he is -- is he kidding? He can't debate Barack Obama because he's got to go to Washington and save the economy? It's like the biggest 'dog at my homework' in history.
