Here is video of former Arkansas Gov. Mike Huckabee on Geraldo where he slammed CPAC as becoming "more Libertarian and less Republican" - which he cited as a reason he chose not to attend this year. He also criticized CPAC for what he called a "Pay for Play" culture that allows sponsors to pay money and obtain podium time.
Huckabee ignores the fact that CPAC is the "Conservative Political Action Conference," which provided a platform for a broad range of opinion across the conservative spectrum. You had everyone from Ron Paul to Newt Gingrich, Mitt Romney, as well as Bill Bennett, John Bolton, Dick Cheney, and many others. It is not a conference put on by the Republican Party. But the message throughout the conference was clearly that conservatives must be united in electing Republicans to Congress this Fall to stop what the Democrats are trying to do.
