Everyone deserves a second chance. And Republican incumbent Sen. Thad Cochran gets his on Tuesday, in a runoff with Tea Party favorite Chris McDaniel in Mississippi for the GOP Senate nomination. Neither man won enough votes in the first round to claim victory in a battle reflecting conservative ideological splits nationwide. In this case, it’s between a GOP fixture known for funneling millions of federal dollars into state programs and a hotheaded young Tea Partier. Even celebrities have been jumping into the ring — NFL legend Brett Favre describes Cochran as a “proven and respected leader” in a new ad.
