Maryland voters gave their public schools what could be a $660 million annual gift when they approved a measure to open five gambling halls throughout the state.

The Associated Press is reporting that the ballot question passed. The measure will dedicate the revenue generated from the 15,000 slot machines voters authorized to the state’s public schools. The Maryland question would create the most revenue of the several gambling-for-school-funding measures before voters in today’s election, according to Michele McNeil’s Ed Week story from last month.

Still to come: Results from Arkansas, Maine, Missouri, and Oregon.
