Why are Herman Cain's advisers secret?

HANOVER, NH (By Byron York, Campaign 2012) - Presidential candidates often make public the names of their top policy advisers as a way of conferring credibility on their positions. Not Herman Cain. At the Republican debate in New Hampshire Tuesday night, the Georgia businessman -- and new frontrunner in the GOP race, according to the latest NBC News/Wall Street Journal poll -- not only refused to reveal the names of the economic advisers who helped him devise the 9-9-9 recovery plan. He also said he has specific candidates in mind to head the Federal Reserve, but insisted those names must also be kept secret. Asked after the debate why his advisers' identities must be kept secret, Cain told me, "If people want to beat me up because I'm not spilling my guts about who it is that's helping me put these ideas together -- beat me up."
