How Trump wins the West, even if he loses

Cruz has long said — and the party has long hoped — that he’ll be able to beat Trump once they get in a one-on-one matchup.

He won’t get it in Arizona. Kasich has sat out the contest almost entirely, but it’s a former rival, not a current one, who threatens to siphon support from Cruz: Marco Rubio.

Arizona has one of the longest early-voting periods in the nation, and experts estimate a majority of the ballots have already been cast, including many sent before Rubio ended his campaign on March 15.

Still, Trump’s opponents can take hope in the unknown: The Arizona primary has had few polls, the most recent one was weeks ago, and the contest’s polling has been hit-or-miss, anyway.
