Fine. Ignore Cruz’ intelligent approach to Trump and his supporters. I’m sure both he and you are good with single digit support, so there is no need to persuade others to join the cause. Insulting them instead is, after all, so much more gratifying.
Cruz’s response to Trump is the same as his response to his opponents in the Texas Senate race. He finds it more productive to avoid stupid fights and instead concentrate on what he can offer.
FYI, when Cruz began that race, his support in the state was, by some counts, -1, according to the margin of error. He was told by everyone he had no prayer of winning.
But I’m sure you knew that, right? Being a former Cruz supporter...
