The Republican candidate of the moment is ... Newt Gingrich? A new CBS poll finds that support for Gingrich has grown to 15 percent, the same level as Mitt Romney's. Herman Cain still leads, with 18 percent, but his support seems to be ebbing, especially among women and the Tea Party. Since late October, his support among women has gone from 28 percent to 15 percent, and his support among Tea Partiers has declined from 32 percent to 19 percent. Six in 10 Republican primary voters say the charges of sexual harassment against Cain make no difference to their vote, but 38 percent of women say they're less likely to support him because of the charges.
