He will go the Paul Ryan route, and plead for party unity. But he will not give an endorsement by name. IMHO.
That is probably what he will do tonight...say something very tepid—not actually an endorsement—but not a condemnation. I want a verbal I SUPPORT THE NOMINEE LIKE HE PLEDGED TO DO.
Laura Ingraham didn’t mention Cruz by name, but she clearly challenged him to live up to his pledge to endorse Trump.
We’ll see if Cruz has the integrity to do so.
