Greg Corombos of Radio America and Jim Geraghty of National Review are glad Michigan Sen. Carl Levin is retiring after 2014 and that the GOP will at least have a shot at picking up the seat. They also blast John McCain and Lindsey Graham for ripping Rand Paul’s filibuster over constitutional limits on drones. And they have fun with Newt Gingrich claiming he hasn’t ruled out a 2016 White House bid.
