Did Herman Cain Really Call Wolf Blitzer 'Blitz?

Politico:

Herman Cain, asked about pat-downs and airport screening and racial profiling after Rick Santorum, said, "The terrorists have one objective that some people don’t get, to kill all of us… we should use every means possible to kill them first or identify them first."

He also called Wolf Blitzer "Blitz," and caught himself a few seconds later.

"Blitz, I meant Wolf. Blitz, Wolf, since we're on a Blitz debate," he joked.

When he wrapped up, Blitzer said, "Thank you Cain."
