You are full of crap. Bush has spoken up for jerk Cruz.
Think of it this way — the GOPe is now completely controlled by Cruz the master strategist. Cruz can make the deals and negotiates around the hostiles that tRump can only dream about (and write about in his fantasy novels).
Cruz is the REAL deal-maker, the master negotiator. Just watch him destroy tRump in the convention and take Hillary to the cleaners in the general. Just watch.
