AUGUSTA, Maine (AP) -- Vermont Sen. Bernie Sanders has ridden a big turnout to victory over former Secretary of State Hillary Clinton in Maine's Democratic presidential caucuses.

Sanders beat Clinton by a margin of nearly 2 to 1. He told supporters in Portland this past week that he'd win if there was a strong turnout.

And the turnout was so big Sunday that some voters had to wait in line for more than four hours in Portland.

The vote came a day after Texas Sen. Ted Cruz won the GOP caucuses.

Unlike Saturday's GOP caucuses, the results aren't binding.
