"Without him applying the brakes on Chuck Schumer’s runaway amnesty train in the Gang of Eight, there would have been nothing left to stop an even more terrible bill from passing."
That is NO excuse. Rubio allowed himself to be the face of this bill....which the media gladly reported. He made promises which have not been kept. The border security provisions in this bill are meaningless because the bill gives Janet Napolitano carte blanche to do whatever she wants.
Rubio was either snookered or is of like mind with people who are disengenuous and downright dishonest. Neither of these choices speak well for him nor his ability to one day lead the country.
