The battle lines for California sports betting were officially – and firmly – drawn on Friday. That’s when two Native American groups announced a new coalition to oppose two measures being proposed by commercial gaming in the state.

The California Nations Indian Gaming Association (CNIGA) and the Tribal Alliance of Sovereign Indian Nations (TASIN) said in a statement Friday that proposed initiatives to legalize statewide sports betting – including mobile wagering – threaten tribal gaming. They pointed out that such gaming generates billions of dollars for state and local governments, employs 125,000 workers, and helps sovereign nations be self-sufficient.
