This sure is one low-energy robocall by Mitt on behalf of Kasich:

Laughable.
A vote for Kasich is a vote for a contested convention and a stolen nomination. Cruz is wasting ammo even mentioning Kasich.
Cruz may have realized that every candidate who has attacked Trump hard leaves the race within weeks. This list is rather long. Kasich would have left as he’s beaten too, but he’s being supported by the donors to try to deny Trump and Cruz delegates.
