No. Ted Cruz should have gotten involved. In war, the army that can muster superior forces at the point of conflict wins, that is how insurgents defeat a modern military. Liberals around the nation attacked Arizona mercilessly while most conservative big shots stayed silent, hence they won, and will always win unless things change.
Once Arizona legislators who voted for the bill started pleading with the governor to veto it, the battle was lost.
There was no point in Cruz, or any other national conservative getting involved.
Put the blame where it lies -- on the Arizona legislators who didn't plan for the onslaught they should've known were coming and, worse, proved unable to defend their own bill.
They "Akinized" themselves...
