Cain still leading in polls: CBS

Herman Cain is still leading in the polls, despite the sexual harassment allegations against him, according to a CBS News Poll.

According to the poll, 18 percent of likely Republican voters supported Cain, 15 percent supported Mitt Romney and another 15 percent supported Newt Gingrich.

The margin of error is plus or minus 5 percentage points.

Both Cain and Romney have lost support since last month's CBS News poll, while Gingrich has improved his standing by 7 percentage points.

However, 70 percent of those polled said that they might still change their minds.

According to CBS News:

Cain has lost support among women since late October. Then, he led among women, garnering 28 percent of their support. Now, his support among women is just 15 percent. He has also lost ground with conservatives, from 30 percent to 23 percent now. And there has been some movement among Tea Party supporters as well; their support for Cain has declined from 32 percent to 19 percent. Romney has lost support among men, while Gingrich's support among that group has increased eight points. 

However, 61 percent of Republican primary voters said that the sexual harassment accusations against Cain won't make any difference. Thirty percent said that charges make them less likely to back him, and that rises to 38 percent among women.
