Gov. Rick Perry's Memory Stumble...Fatal?

Texas governor Rick Perry may have made a fatal gaffe at the Republican presidential debate Wednesday night.

In the midst of answering a question about reducing the federal deficit, Perry reminded the audience he had a plan to cut three government agencies immediately upon becoming president. But while he reeled off the Department of Commerce and the Department of Education, he could not remember the third.

"It's fatal," said Tony Fratto, a former White House spokesman for the Bush Administration. "If it happened on its own he may have survived .... but there have been a series of gaffes and this is probably fatal."

Another Republican strategist agreed.

"It was the death knell," said Sara Fagen, former director of political affairs for the Bush Administration. "Perry had the opportunity to re-emerge at this debate...and he squandered that opportunity."

Later in the debate, presented by CNBC at Oakland University in Michigan, Perry offered that the third agency was the Department of Energy.

Immediately after the debate, the governor told members of the media who had gathered in the "spin room" that he had "stepped in it out there."

Taking full responsibility for his slip-up, Perry went on to say, "I stepped in it man, it was embarrassing, of course it was."

Trying to get the conversation back to his message Perry told reporters, "the bottom line is I may have forgotten energy but I haven't forgotten my conservative principles" adding, "I'll be in SC on Saturday and hopefully I'll remember the energy department."
