Romney’s speech was designed to stop Cruz, not Trump. Lost in all the attention paid to his attacks on Trump was the revealing fact that he encouraged all three of the other candidates to stay in the race. That counterproductive advice leads to the possibility of a brokered convention where Romney and Ryan could swoop in and snag the nomination, whereas if Kasich and Rubio had dropped out before Tuesday, Cruz would have shellacked Trump and would hold the delegate lead now.
