Trump supporters are the real grass roots here. The Antis are the Bush/Romney open borders cheap labor Establishment. No matter how many times its pushed the false narrative claiming the open borders. cheap labor Bush/Romney led crowd is grass roots, it will never be a truth.
Just noting that which entirely gets ignored by #nevertrumps--he won 40 contests out of 55 (counting territories, DC).
He won nearly twice as many VOTERS as Cruz (not clever delegates).
The degree to which #nevertrumps dismiss those voters is astonishing, and if Cruz himself ever expects to get support from them he had best not dismiss them, even if his foolish supporters do so.
