I’m in Des Moines today and tonight, reporting live from Drake University, where the first Republican presidential debate with Newt Gingrich as a front-runner will take place at 9 pm ET tonight on ABC.  The debate will be moderated by Diane Sawyer and George Stephanopoulos, but the real question will be whether and how hard each of the other candidates will go after Gingrich in an attempt to damage his momentum.  That pattern has repeated itself with the other boomlet candidates, but the other boomlet candidates didn’t have Gingrich’s talent for debate.  Will they shy away from direct attacks tonight, and if they do attack, how will Gingrich respond?  I’ll preview the stakes for each of the candidates tonight:

Two candidates won’t appear in tonight’s debate.  Herman Cain suspended his campaign and will likely announce an endorsement in the near future.  Jon Huntsman will conduct a townhall in New Hampshire, having not met the threshold of polling support in Iowa to participate tonight.

Before tonight’s debate, several of the candidates will attend a forum sponsored by Veterans for a Strong America.  I’ll also be there, and hope to have video and first-hand reporting from the event later this afternoon.  Stay tuned.
