Rubio had a bad night last night. He can come back from it, but his path is harder, not least because now neither Kasich nor Jeb will quit.
So, as Mr. W. points out, Chris Christie may turn out to have done a serious disservice to the country twice. First he got Obama re-elected in 2012, and how he's undermined Rubio (and he didn't even help himself), possibly giving us a Trump nomination.
What a vindictive poseur. Right for NJ, wrong for America.
