Jim Geraghty of Radio America and Greg Corombos of Radio America welcome the news that Tennessee Sen. Bob Corker will not become "the Brett Favre of politics" as the senator confirms he will honor his initial decision not to run for re-election this year.  They also discuss efforts by House Democrats to ban every semi-automatic firearm that has a detachable magazine and every one that can hold more than ten rounds, with Jim detailing the random, uninformed approach Democrats appear to be taking on this issue.  They have some fun with the news actress Stacey Dash and former MSNBC hothead Dylan Ratigan are running for Congress.  And they pay tribute to National Review Founder William F. Buckley, Jr. ten years after his death.
