After Massachusetts passed the casino law in 2011, the opposing views on expanded gambling seemed like a moot point. But the question of casinos is now very back in play with Ballot Question 3. Opponents are pushing a "Yes" vote, which would repeal the state’s casino-gambling law. For their part, supporters are doing everything possible to keep the law on the books. 

John Ribeiro is the chairman of Yes on 3 campaign, which sponsored the ballot question.

Frank Callahan is president of the Massachusetts Building Trades Council, which opposes Question 3.
