I think Rubio is making a strategic error. I agree that he should have gone after Trump earlier, but he did not have to stoop to Trump-level standards. He could have attacked Trump on substance, and substance alone. It would have given the people a show, which they apparently want, but without degrading himself in the process. Instead, he has started dabbling with Trump Lite at his rallies.... maybe Rubio will get his act together but he is running out of time.
