Whenever one of them does as you pointed out, they show who the die-hard Cruz folks are and we get to rebut them.
It's easy to have a lapse and deem something that is un-Constitutional is right because it seems to make sense in the heat of the moment - remember, there is no "Noble Cause" clause in the Constitution....either you believe in it or you don't. It never promised lack of friction - in fact it guaranteed our right to cause friction.
Ignoring people is shutting them down?
It is foolhardy to think that Donald Trump or Ted Cruz or anyone else can save what’s left of America. We are on the verge of Civil War, a war that will not end well. The only way to prevent an all out slaughter is to have that war earlier rather than later: in the streets. There should be push back, measure for measure, and then some. If Occupy puts ten thousand in the streets, the Right must put fifty thousand in the streets. Reciprocate, and overwhelm. May I offer the words of that great Black father of our party, Fredrick Douglas: “If there is no struggle there is no progress. Those who profess to favor freedom and yet depreciate agitation are men who want crops without plowing up the ground, they want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one, or it may be a physical one, and it may be both moral and physical, but it must be a struggle. Power concedes nothing without a demand. It never did and it never will”.
