Are NeoCons Rigging the Primaries Again?

Cruz won and Trump, according to FoxNews, lost. Trump took the 2nd place standing with grace, but he lost mostly because of the surprising surge by Rubio. How can a candidate polling much lower only hours before, and then suddenly garner an impressive score? Could it be that Rubio and the Republican Establishment had a little help from one of their 'open borders' corporations? It may be so much hullaballoo, but I've seen the NeoCons steal primaries before (from Ron Paul).
