Very quick:

• Chris Christie is auditioning for the VP spot.  He also constantly went back to whaling at the Democrats at every opportunity.
• Mike Huckabee was very… folksy. The closing statement was a little… interesting.
• Bobby Jindal more or less was going after Christie. Might work, might not. Jindal certainly knows his stuff.
• Rick Santorum yells a lot.

Fox Business Network actually asked smart questions, and when they tried to ask a dumb one the candidates smacked ’em down right quick.  Refreshing. All in all, a hopeful sign for the 9 PM debate.
