Maybe they mean Cruz rose to #2? Thing is, it seems to have happened because some Rubio support went to Kasich.
Astute. And in keeping with my conspiracy theory of the past few days.
By laying off Kasich, and letting him "win" the debate (which I think he did) Trump has enabled Kasich to eat into Rubio's votes.
It's all about Florida. A stronger Kasich means a weaker Rubio in Florida.
I don't think Trump even cares if Kasich wins Ohio, because I think he'll be the VP selection. After the Florida and Ohio primaries on Mar 15, they make the deal.
