It's not a "Rubio scheme," it is a "NeverTrump scheme," and Cruz is the designated beneficiary of it. The only reason Cruz is able to hide his hand is that Kasich is in reasonably good shape in Ohio.
CNN covering the GOPe #NeverTrump scheme now.
“and Cruz is the designated beneficiary of it.”

The only way Cruz will benefit is if Lilltle Marco and Mailbags Johnny move aside and let him compete head to head against Trump. Sure Cruz wants to beat Trump, but he’s the only one besting him with any consistency and is in 2nd place. By plotting the vote this way, Rubio and Kasich are not in league with Cruz, rather they are trying to deny both Trump & Cruz...no 1,237...then the RNC decides! Welcome President Clinton!
