The real question is whether Rush wants to retire or not. People will give him one chance to get this correct. Let him support Cruz, but let him do the same thing as the decent Cruz folks did here. Be better than their candidate and blame the riot on Soros and Bernie supporters.
BTW, there is no "violence." There has never been any violence at Trump's rallies. Trump has never told his supporters to disrupt other candidate's rallies. People see what's going on in Baltimore and Ferguson and they're not going to lie down for these thugs which is why Trump told them to fight back.
