 Former Minnesota Governor Tim Polenny says he won't run this year for the U.S. Senate seat vacated by Democrat Al Franken. The two-term Republican governor and one-time presidential candidate had considered a bid in the week since Franken resigned due to sexual misconduct allegations. But he told Fox Business on Tuesday that he wouldn't run this year. He cited the 10-month sprint to election day in a tough state for Republicans. State Senator Karen Housley is the only Republican in the race. Democratic Senator Tina Smith was appointed to immediately replace Franken. She's also running for the seat in the November election.
