The undercard debate saw New Jersey governor Chris Christie, former senator Rick Santorum, former governor Mike Huckabee and Governor Bobby Jindal swap ideas on taxes, entitlement reform and reducing the size of government.

Jindal was on a mission to distinguish himself from the rest of the GOP field by insisting he was the only one in the field who actually reduced the size of government. He repeatedly declared that it is “not enough to elect ANY Republican,” citing the lack of action by the Republicans currently in Washington. He attacked Christie several times for his record in New Jersey, comparing it unfavorably to his own record in Louisiana. Jindal drew disapproving “oohs,” when he told Christie, “Chris, I’ll give you a ribbon for participation and a juice box.”

Christie refused to take the bait, praising Jindal for the work he’s done, and adding levity in the face of Jindal’s intense attack, saying, “I complimented Bobby. Imagine how much time he’d want if I’d actually criticized him!” Christie then pivoted, as he did all night, to Hillary Clinton. A full 13 times Christie mentioned Clinton, warning Americans she was “coming after your wallets,” describing how she was aiming for more government control over our lives, and thinking “she knows better how to run your life than you do.” Christie insisted he would challenge Hillary on her ideas and as a guy whose won big in a blue state.

Santorum had a wonderful response to a back and forth between Jindal and Christie. Jindal was arguing the GOP needs to select a conservative. Christie was arguing the party needed someone capable of winning in blue states. “This is a real legitimate debate between Chris and Bobby, and if somebody says we need someone who can win in a blue state, and Bobby says we need a real principled conservative….”

Santorum then smiled and spread his arms wide.

Santorum had another strong moment in this business debate when he said “The most important business is the family.” He explained how the breakdown of families has been economically crippling, and declared that we need to “return dads into homes.”

The always folksy Mike Huckabee laid out his fair tax ideas and passionately thanked our vets, “They kept their promise to us. We didn’t keep our promise to them.”

Perhaps the debate’s strongest moment was the last, when Christie offered his closing remarks:

I want to tell the American people who are watching tonight the truth. I saw the most disgraceful thing I’ve seen in this entire campaign a few weeks ago. Hillary Clinton was asked the enemy she’s most proud of, and she said, “Republicans”.

In a world where we have Al-Qaeda, and ISIS, the mullahs in Iran, and Vladimir Putin — the woman who asks to run and represent all of the United States says that her greatest enemies are people like you in this audience, and us here. I will tell you one thing, and write this down, when you elect me President of the United States, I will go to Washington not only to fight the fights that need fighting, not only to say what I mean, and mean what I say, but to bring this entire country together for a better future for our children and grandchildren.
