Tracking the GOP race to 2012

Potential 2012 hopefuls will attend the Values Voter Summer in DC Sept. 18-20--the lineup includes Eric Cantor, Mike Huckabee, Bobby Jindal, Sarah Palin, Tim Pawlenty, Rick Perry, Mike Pence, and Mitt Romney; Haley Barbour dined with some senior GOP strategysts in DC Monday night; he held a press conference with GOP lawmakers today and said he'll "probably never" announce he's running for president; John Ensign apologized for his affair privately in a meeting with GOP senators; and he accused a former senior aide--the wife of the staffer with whom he had the affair--of extortion.
