Did Cain flip-flop on Fed comments?

A video put together by the Huffington Post says Herman Cain lied during the debate Tuesday about his past statements on auditing the Federal Reserve.

The full context of Cain's remarks in the second clip of the video (that appears to be taken from his former Atlanta-based radio show) may not be included. What we can take from it, is that while Cain never used the word "ignorant," -- as Ron Paul said -- he did say those who want to audit the Federal Reserve "don't know enough about it." That's kind of the same thing.

Was it a flip-flop? Here's the video via BLAZE reader Okie from Muskogee:
