Gov. Perry on debate performance 'I had a brain freeze'

Political observers are already calling it one of the biggest debate gaffes in modern history. During the debate in Rochester, Michigan on Wednesday night, Rick Perry said he would eliminate three federal agencies if elected President - but after struggling for nearly 50 seconds, he was able to name only two of them. Now many are saying this could well mark the beginning of the end of the Texas Governor's campaign.

Rick Perry explains to Christine Romans this morning why he's not dropping out of the race – and why voters will ultimately choose a candidate who realize that this country needs "substance more than we need style."
