If Cruz really was behind this, I would drop him like a hot-potato.
Behind what? The reaction he got in the Bronx? Of course he is in no way responsible any more than Trump is. The Left has been disrupting GOP campaign events for many years. I have seen them firsthand.
In 2012 I attended a Romney campaign event in VA outside DC. People were lining the street with pro-Romney signs outside the entrance to the event, which was held outside. Suddenly. several buses arrived filled with black demonstrators (about 150 of them) who came with megaphones shouting No Justice, No Peace. They deliberately stepped in front of the people holding the pro-Romney signs to block them from view. It was a tense situation and the police did nothing about it.
Did Romney bear responsibility for these demonstrators? Why don't we see similar disruptions by the "far right" at Dem campaign events?
Again, stop peddling this crap that Trump or any Rep is responsible for these agitators who are bent on inciting violence and shutting down free speech.
