It's not anti-Trump. It's pro-conservative. Trump is not a conservative. Cruz is.
Do not delude yourself. “NeverTrump” is not pro-Cruz, its Pro Paul Ryan. Romney, etc. Hes not winning a contested convention. The GOPe is a Snake - its already turning on the Cruzaders by rigging the rules and stacking the delegates with long-term party insiders.
Bottom line, Cruz is NOT going to win, His chances died with his horrible performance in the South. From here all the dedicated Cruzaders are doing is fighting to elect Hillary. Since the RINO the GOPe will force on us at a convention will not win in the General.
