Yep. It's pretty well understood that the gravy states are all behind Cruz, and that now, he's got a real uphill climb ahead. Couldn't come at a worse time for Ted, either, as nearly all the states after the 15th are more Trump friendly.
Based on every bit of polling I've seen over the last couple of weeks, Ted has no chance of winning either Florida or Ohio. About the best he can hope for in those states, is to come away with a half way respectable showing, not that it will do him a whole lot of good in later states that Trump will almost certainly dominate.
The prospects going forward, have got to look pretty daunting to Team Cruz. Perhaps that's why he went full kamikaze on Trump at the debate tonight. He knows the math isn't there for him to get to 1,237, so he's got to try and beat Trump some other way.
In light of all this, Ted's movement toward Bush Inc. and the RINO establishment, makes perfect sense. He's out of options, and has nowhere else to go.
