Cruz might have not been as successful in PA, OH, Michigan, and Wisconsin. He did not fair well at all in the primaries in any of them.
Anyone who is an honest and truthful conservative will admit that none other than Donald Trump would have beaten Hillary Clinton. None of them. Only Trump had the brass set necessary to go up against the world and win.
Cruz was very well hated in Florida, not winning a single county.
No Florida = No win USA
