I won't give my usual debate post-mortem because I did not see the debate in its entirety. Due to a previous commitment, I only caught the last half hour of the debate. I have subsequently watched much of it online and here are my observations.
1. Marco Rubio Got Bloodied Again
For the second debate in a row, Marco Rubio got bloodied. Last time around, it didn't affect him so much as he finished a strong third in Iowa. I'm not so sure lightning strikes twice. Chris Christie popped him hard and his counterpunches weren't particularly effective. Christie spent much of the night comparing Rubio to Barack Obama (i.e. first term Senator). Rubio should have said, "During this campaign, you have called Barack Obama feckless. Did you call him feckless after you hugged him during Hurricane Sandy?" But Rubio isn't a street fighter and tonight it might have cost him.
2. Chris Christie, Jeb Bush and John Kasich All Had Good Nights
