Chasing cars?

There's a line about dogs that chase cars -- what will they do with one of they catch it?

 

Christopher Hitchens is suggesting Barack Obama may well be in the same position.  He's caught the Democratic nomination, and isn't quite sure what to do with it.

By the end of that grueling campaign season, a lot of us had got the idea that Dukakis actually wanted to lose—or was at the very least scared of winning. Why do I sometimes get the same idea about Obama? To put it a touch more precisely, what I suspect in his case is that he had no idea of winning this time around. He was running in Iowa and New Hampshire to seed the ground for 2012, not 2008, and then the enthusiasm of his supporters (and the weird coincidence of a strong John Edwards showing in Iowa) put him at the front of the pack. Yet, having suddenly got the leadership position, he hadn't the faintest idea what to do with it or what to do about it.
