Is anyone willing to argue Cain is still in this race? Yet another poll shows Newt up and Cain tanking.

Gingrich attracts 26 percent of the support from Republicans and GOP-leaning independents in a Quinnipiac University poll released Tuesday. A Quinnipiac poll taken earlier this month found Gingrich with just 10 percent of the vote. Former Massachusetts Gov. Mitt Romney garners 22 percent, shedding a point since the last poll. Herman Cain falls to third place with 14 percent, dropping 16 points since early November, when he led the field. None of the remaining candidates receives more than 6 percent of the support. Nineteen percent of voters remain undecided.

Watch for an updated PDC shortly. And remember, the PDC isn’t just a straight average of polls. It takes into account age of the polls and the sampling.
