I wrote the other day how it’s very odd that Rubio hasn’t endorsed Cruz. I should note that there is some concern that if Rubio endorsed him, the Florida senator would lose control of his delegates, which the Cruz campaign wants him to hang on to, lest some of them potentially go to Trump. (In Arkansas, the Rubio and Cruz forces have been cooperating on trying to box out Trump.)
