Can Perry's campaign recover from epic debate 'brain freeze'?

This morning, political watchers can't stop talking about Texas Gov. Rick Perry this morning. Last night at the CNBC GOP presidential debate, Perry suffered from a serious bout of brain freeze when he couldn't name the third government agency that he himself had previously vowed to eliminate.  ven Perry, never the strongest debater, admits that he really "stepped in it" last night.

This morning, Ali Velshi asks CNN contributor John Avlon, Republican strategist Karen Hanretty, and columnist Ruben Navarette if Perry remains a viable candidate – or if his campaign finished.
