Former Democrat candidate for Iowa governor Nate Boulton says he needs more time to decide if he'll stay in the Senate. Allegations of sexual misconduct ended his campaign for governor Thursday, but Boulton was noncommittal about his future as a lawamker. He told KCCI-TV in an interview he'll need to discuss a decision on his Senate future with his wife Andrea. She participated in the interview as well and also committed to a discussion about her husband's political future while sounding optimistic that he could continue to serve.
