Whenever a heated disagreement erupts on a political talk show, the hosts and the sideliners always say “all right, tone it down, take a chill pill.” MSNBC’s Chris Matthews: “Romney’s birther joke…was awful. It’s an embarrassment to your party to play [the] ethnic card.” RNC chairman Reince Priebus: “I’m not going to get into a shouting match with Chris so you guys can move on.” Matthews: “Because you’re losing, that’s why.” Priebus: “Garbage, garbage.” Matthews: “It’s your garbage.”
