Come, I will conceal nothing from you: it’s looking hard for Ted Cruz to win Arizona at this point. Not impossible, but we don’t know how the early voting went and people are legit worried that Marco Rubio banked too many of those. Keep an eye on how well John Kasich does in a vacuum: he didn’t bother to campaign in Arizona, so that’s useful info to know. Utah looks better. Heck, Utah looks like an easy Cruz win at this point. And Kasich did spend money there. As for American Samoa… nobody knows, and anybody who says that he does is just lying to you.
Bottom line is, whatever happens tonight – maybe late tonight, so be prepared for that – the race goes on and everybody moves on to Wisconsin. Unless Kasich runs out of money before then, which would be frankly lovely for both the Republican party, and the Republic itself.
