This is an interesting development, not because I think it means Clinton is going to win, I don't, but because it is an interesting aboutface in spin tactics:

** Hillary Clinton's team has revised its turnout model. The same senior campaign source who projected a turnout of 140,000 voters is now predicting that 150,000 voters will show, and says that, according to the turnout model the campaign is employing, Clinton will finish a strong first on the strength of turnout from Democrats. Two days ago, Obama's chief strategist, David Axelrod, told me that the Obama turnout model assumed about 150-155,000 people too. Clearly, the more independents who turn out, the better for Obama. The more Democrats -- the more new Democrats -- the better for Hillary Clinton. An Edwards aide said the campaign predicts that 135-140,000 Dems will caucus.

Why spin up? My guess? They felt they were being hurt by trying to lower expectations. For the record, each campaign is projecting a record turnout, 122,000 caucused in 2004.
