Breitbart understands Ted Cruz better than Politico.
Republicans from red states have often gone to Washington vowing to change it, only to have Washington change them. Even Grieder admits to being surprised that Cruz actually means what he says and is not "all hat no cattle" when he declares that he is "not at all" afraid of losing fights after standing on principle.
Cruz said something to get elected, and planned to follow that in Washington.
What a surprise?
