Boulton vows to stay in Senate

Des Moines Democrat Nate Boulton says he's staying in the Iowa Senate despite the fact that he suspended his campaign for governor after two women accused him of sexual impropriety, and his party's leader in the Senate is calling for him to resign.  Boulton blames his actions on binge drinking...and says he hasn't had a drink "in months." Senate Democrat Leader Janet Petersen says she's "disappointed" in boulton.  She says he'll have to face the "people in his district" and a "possible independent investigation."
