Early indications are such that Cruz will win Kansas with ease. Polls are still open in the other states.

But Kansas, Maine, and Kentucky are Caucus states where organization counts more than primary states.

Nate Silver explains in Semi-Super Saturday: Semi-Live Coverage

We now have 12 percent of precincts reporting in Kansas, and it looks like Cruz land. He leads 50 percent to Trump's 25 percent and Rubio's 14 percent. Not only that, but Cruz holds a significant lead in all three of the congressional districts currently reporting results. Unless something changes significantly, Cruz is going to win Kansas with ease.
