Republican presidential candidate Herman Cain makes it clear in his new book that Texas Rep. Ron Paul’s supporters annoy him with their “stupid” questions about the Federal Reserve.

Cain, the former Godfather’s Pizza CEO, writes that Paul’s supporters are “threatened by me” and are “trying to destroy me on the fact that I was once affiliated with” the Federal Reserve.

Cain was chairman of the Federal Reserve Bank of Kansas City in 1995 and 1996.

The Daily Caller obtained an advance copy of Cain’s book, “This is Herman Cain,” which goes on sale Oct. 4. In the manuscript, Cain claims Paul’s campaign “sends one of its ‘Paulites’ everywhere I show up.”

Paul is a proponent of auditing the Federal Reserve.

“I get the same stupid question at almost every one of these events,” Cain writes. “I know it’s a deliberate strategy. How can a person randomly show up at a hundred events and ask the same stupid question to try to nail me on the Federal Reserve? It’s really becoming annoying more than anything else.”

Cain said Paul’s fan have “stretched the truth” by accusing him of not wanting to audit the fed.

“I have never said that,” Cain wrote. “I have said: ‘I don’t think you’re going to find anything to audit on the Federal Reserve.’ But they want you to believe that Herman Cain doesn’t want the Federal Reserve to be audited.”

A spokesman for Paul did not immediately return a request for comment.
