Yes, I'll be waiting to see how the Big Three (Clinton, Obama, and Edwards) handle themselves tonight, but the candidate I'm most interested in seeing on the stage is Bill Richardson. He's running a very distant fourth in the low single digits in the national polls, but he's jumped up to third place in Kos's latest straw poll based in part on a very well received performance at Moveon.org's recent online forum on Iraq.

Richardson also just went up with a pair of ads in Iowa and New Hampshire to raise his profile further. Here they are:

In many ways tonight is a no lose for Richardson. All of the focus, pressure and expectations are on the Big Three, and with that comes very little upside and a potentially significant downside. So if Richardson can find a way to differentiate himself tonight in a positive way, it could help build on the little boomlette he's got going with the Democratic base.
