In a situation that political and gaming consultants say they haven’t seen before, both major parties in California have now come out in opposition to Proposition 27, the statewide mobile wagering initiative backed by the a group of seven commercial operators.

Late Friday, the California Republican Party announced its opposition, joining the Democrats, who stated their position in late July. The Democrats also said they will remain neutral on the tribal-backed, retail-only Proposition 26. The Republicans voted to oppose it.

“Prop 27 breaks the promise made to California’s Native American tribes to grant them the sovereign right to operate gaming in California in order to improve the lives of their communities across the state,” Jessica Millan Patterson, chairwoman of the California Republican Party, said in a press release.
