Romney had, at the most during the early primaries, no more than a quarter of the primary votes. The only way Romney won the nomination was that the establishment GOP continued to pay vanity candidates to enter the race pretending to be "the" conservative candidate -- the slate-of-eight, against one RINO GOP-e non-candidate. Romney lost the general election against the absolute worst Democrat candidate in the history of the USA. Any one of the slate-of-eight might have won, if running as the lone conservative.
Cruz is the lone conservative in this race. As I previously predicted, Walker just cannot stop pandering and pretending, and cannot articulate a consistently conservative message. The rest of the potential candidates are even worse, far worse.
