Interesting results ( at 76% reporting).
"Establishment" - 46%
Trump - 34.5%
Cruz - 11.5%
So in essence, "Establishment" 46%, outsiders 46%.
If the real battle here is outsiders v. "the establishment", then that's the only way you can view the vote.
Trump and Cruz may be both outsiders, but they don't appeal to the same voters.
It's a long game.
