Businessman Herman Cain defiantly denied sexual harassment allegations against him on Tuesday and vowed they would not force him to withdraw from the race for the 2012 Republican U.S. presidential nomination. "Ain't going to happen," Cain said, referring to the chances of giving up his presidential bid. "We will get through this." Cain spoke at a news conference to respond to Sharon Bialek (pictured), a Chicago woman who went public on Monday with allegations that Cain made a crude sexual advance against her in 1997 when he was head of the National Restaurant Association. She is the fourth woman to accuse him of sexual harassment/Reuters. More here.

Question: Is it possible all these women are lying?
