A new CNN/Opinion Research Corp. survey shows Obama "remains competitive in hypothetical 2012 presidential election matchups, especially against Sarah Palin." 

The poll, which was released Thursday, sets Obama against Mike Huckabee, Mitt Romney, Newt Gingrich and Sarah Palin, four Republicans who may be in the running for the GOP's top spot in 2012.

The results show 21 percent of Republicans saying they'd support Huckabee, 20 percent supporting Romney, 14 percent supporting Palin and 12 percent supporting Gingrich.

From CNN:

"In a possible general election showdown, Obama leads Palin 52-44 percent among all registered voters…In a hypothetical 2012 matchup, Huckabee leads Obama 52 – 44 percent, while Romney has a 50-45 point advantage, which is within the poll's sampling error. Obama hold a 49-47 percent margin over Gingrich."
