And he can choose to answer or not answer questions about his values and beliefs in that role as candidate for office.

I think in this case, they are symptomatic of a residual anger against the political classes that are destroying our country. Cruz was elected in 2012 and has not been successful in leading Republicans; he just keeps asking for more money to further his own career, promising that if he is promoted then he will make a difference. He is a career politician and government employee. I'm not interested in furthering his career by providing more money.
