Mohegan Sun and Suffolk Downs are celebrating a strong vote of support from Revere residents for a proposed $1.3 billion resort casino, but other hurdles lay ahead for the project.


About 63 percent of voters backed the casino in Tuesday's referendum, topping the margin of victory in a November vote on an earlier proposal that would have straddled the Boston-Revere line.  The plan was rejected by East Boston residents, prompting a new proposal entirely on the Revere side of the border. 


The Mohegan Sun plan will now compete with Wynn Resorts for the sole eastern Massachusetts casino license to be awarded by the state gaming commission. Wynn has proposed a casino along the Mystic River in Everett.
