Donald Trump is blasting a "corrupt" election system for complicating his path to the Republican nomination.
Trump tells a crowd of thousands of enthusiastic supporters gathered in a frigid airport hangar in Rochester, New York on Sunday afternoon that "it's not right" that the person who wins the most votes may not be the nominee.
He says he's doing fine, but if he's denied the nomination, "you're going to have a big problem, folks."
While Trump has won more states than any of his Republican rivals, it's possible that he won't secure the 1,237 delegates needed to win the nomination before the summer convention.
Rival Ted Cruz has been out-maneuvering him at local and state gatherings where delegates are being chosen. Trump recently hired Paul Manafort to craft a strategy to win more delegates.
