Cruz is the same yesterday and today, a consistent constitutional conservative the winds of liberalism will never blow strong enough to turn him from his rock solid principles, he will not go along to get along even if it means he could lose an election, where others may for political expediency twist and turn into some perceived advantage Cruz will not, no question about it what you see and hear is what you will get.
Most recent case in point, it would have been politically expedient for Cruz to change positions on corn subsidies to win Iowa, but he had the experience of observing others and the wisdom to know in the process of sacrificing principles for winning he would have lost everything. Yes he did say he would wean them off subsidies over five years but that is just good common sense, reason and logic whatever the issue he is not going about selling pigs in a poke.
