It mean that if Trump does falter (and that's a big IF), Cruz stands to be the new frontrunner - keeping the GOPe well in the distance.
And what about Jebbie's big comeback? I don't see any indications of it here. He's even trailing Rand Paul!
I stopped worrying about that a couple of months ago. Only Rubio is left, and his GOPe full court press against Cruz only backfired.
