The campaign that could bring legalized sports betting to California has become the most expensive ballot-initiative fight in state history, pitting wealthy Indian tribes against online gambling companies in a contest over what could become the nation’s most lucrative marketplace. The Yes on 26, No on 27 committee, sponsored by more than two dozen Indian tribes, has raised about $108 million through this month, state records show. Federated Indians of Graton Rancheria is among the major donors. (AP Photo/Eric Risberg,File)
