We have final results for Maine. Cruz (45.9%) wins convincingly. Trump (32.6%) 2nd. Kasich (12.2%) 3rd and Rubio (8%) 4th. Rubio was the only candidate to fail to surmount the 10% threshold and is shut out for delegates.
One thing to note is that all the votes for those four combined were just over 17,000 people. So small state combined with a caucus. So just a tiny number of people voting. But those are the rules.
