A group wants to ask Arizona voters to allow gambling at private casinos and racetracks.
The 50-page initiative was filed with the state Friday, but a leader of the effort says a revised version will be filed Tuesday to make changes that include a new name for the group.
Organizers would have to collect nearly 173,000 signatures for the measure to go on the November ballot.
The initiative's summary argues that allowing only Indian tribes to run casinos creates an unacceptable monopoly. It says allowing racetracks and private casinos would create jobs and tax revenue for education, police and other uses.
Carl E. Nicholson is listed as chairman. He describes the initiative drive as a grassroots effort but says members expect backing from dog-track operators and Las Vegas casinos.
