Just hours before the General Assembly wrapped up the legislative session, lawmakers approved a massive, controversial gaming bill that legalizes sports wagering and allows a new Terre Haute casino.

The issue divided both parties, as lawmakers instead split by region and beliefs on the expansion of gambling. Even Rep. Todd Huston, a prominent House Republican who helped finalize the language, voted against his own bill in the end.

House Bill 1015, one of the largest gaming bills in decades, moves up the date that horse race tracks are allowed to use live table games and caps the number of casinos and racinos a gaming operator can own at six, instead of at just two casinos. The result: One operator could have a large share of the industry responsible for a huge source of Indiana’s taxes.
