I have just finished live tweeting the GOP undercard debate which aired on FOX Business Channel and here is my post-mortem.
Rick Santorum - When the former Pennsylvania GOP Senator wasn't partying like it was 1995, he was shouting in the microphone likely causing permanent hearing damage to some poor tech guy.
Mike Huckabee - The former Arkansas governor was his usual affable self and had a very good line about Congress reforming the VA if Congress were to have VA health care. He also drew laughter when he said that he heard Fed Chairman Janet Yellen's name he thought of his wife Janet because she does a lot of yellin'. Huckabee called for Yellen, not his wife, to be replaced as Fed Chairman. Despite this I suspect Huckabee might be permanently consigned to the second-tier.
