Perry was the first to blister Trump, then Jindal. How did that work out? Cruz will continue to avoid Trump as much as possible until the last. Trup and Cruz met remember; maybe they agreed to a semi-peace truce until the others are out of the way. Cruz will continue to play it low and let his opponents self destruct. Rubio may be the exception and become his first main target because of the establishment connection. Whoever is left at the end, Cruz will take on in a debate style, attacking policies rather than character. He will keep an air of professionalism about him.
