All of the big news networks are covering the debate as if it was some sort of political playoff game, but the truth is that Thursday's debate probably won't move the numbers much at all.  Nothing of substance was said that wasn't said in previous debates, and there were no defining moments that will significantly change the course of the campaign.

Real Clear Politics keeps a running average of all the recent major national polls, and according to them none of the other candidates is even close to double digits right now.  It looks like it is going to be a three way race between Biden, Sanders and Warren, and Warren appears to be the one with momentum.
