The Republican Race for President: More Unsettled than Ever

Establishment Republicans and other political pros think Mitt Romney is the most likely candidate to unseat President Obama a year from now. We get the latest with the Iowa caucuses less than two months away. In the meantime, a fourth woman has made sexual harassment charges against Herman Cain, this time in a public statement with the ugly details. Sharon Bialek, a former employee of the National Restaurant Association, then run by Herman Cain, said she'd been fired from her job and that her boyfriend suggested she ask Herman Cain how to get a new one. Facing a bank of cameras in New York City, she gave a graphic account of what happened. We hear what she said and what the impact might be and look at how the Republican presidential field is shaping up.
