Rubio knows what’s about to come down about the Cruz cheating scandal. He’s thinking he can show up and “save” the party from Trump. It’s a pretty arrogant strategy and a longshot for sure.
Frankly, the only thing that will save Trump is what no one will mention and will never happen. Cruz needs to drop out and endorse Trump, pledging his delegates to Trump. That puts Trump well over the top, unites Conservatives and kicks the GOPe where it hurts.
Unfortunately Trump burned that bridge and it is going to cost him the nomination. Ted may not win the nomination, but neither will Trump. Cruz will go back being a senator. Trump goes home a bitter, beaten man who thought he could take on the machine all by himself and Win.
