It seems to have started. Donald Trump has charged that Cruz stole the Iowa caucus by outright lies committed by Cruz. Trump wnts Cruz' victory nullified or a re-do of the Iowa caucus held.

Of course, neither of these things will happen.

Trump will most likely tear up his pledge not to run as an independent stating the RNC is unfair and therefore the contract is null and void - just as Trump says he does with bad contracts in business.
