Josh Marshall on Chris Christie's Murder/Suicide Mission

++Josh Marshall today writes that not only did Chris Christie destroy Rubio in the debate but he ended his political career. Josh points to the fact that Rubio came to the Senate in the tea bagger victories in 2010 and since has made it clear he hates the job so much so that he is not running for re-election this year. It is hard to know where he goes from here. Marshall feels he can not parley a third in Iowa and a fifth in New Hampshire into a viable campaign going forward.
