The week ahead

It's going to be a big week for the 2008 race.

On Sunday, the Democrats gather for the CNN/WMUR/Union Leader Debate at Saint Anselm College in Manchester, NH.

On Monday, sources say former Senator and current Law & Order star, Fred Thompson will enter the race with a "testing the waters" committee.

On Tuesday, Republicans take the stage at Saint Anselm for the third debate of the season. Like their Democratic counterparts, the debate is hosted by CNN, WMUR and the Union Leader.
