Republican Debate: GOP Presidential Candidates Face Off In Las Vegas (LIVE UPDATES)

On Tuesday night, seven candidates competing for the Republican presidential nomination are facing off in Sin City in a primary debate.

The following contenders are participating in the Las Vegas event: U.S. Rep. Michele Bachmann (R-Minn.), former Godfather's Pizza CEO Herman Cain, former House Speaker Newt Gingrich, U.S. Rep. Ron Paul (R-Texas), Texas Gov. Rick Perry, former Massachusetts Gov. Mitt Romney and former Pennsylvania Sen. Rick Santorum.

Former Utah Gov. Jon Huntsman will not take part in the debate despite going head-to-head against the same group of candidates in a primary forum in New Hampshire last week.

Tuesday night's event comes in the wake of polls showing Cain rising toward the top of the primary pack. A new CNN survey shows the former Godfather's Pizza CEO running one point behind Romney in the presidential contest. According to the poll, however, two-thirds of Republicans and GOP-leaning independents remain undecided on the contenders running in the race.
