For the first time in California history, a Citizens Redistricting Commission drew the state's legislative and congressional maps this year.  But many Republicans are concerned the State Senate maps could give Democrats a two-thirds supermajority - enough to raise taxes.  So a GOP group has gathered signatures in hopes of forcing a voter referendum next year.  Senator Mimi Walters says she's confident the referendum will qualify.  That means the California Supreme Court would decide what maps to use until voters get their say.

Walters: "What I believe the Supreme Court will do, it will appoint a special master to come in and draw the lines - and have the lines ready by January for the 2012 election."

The same group also tried to challenge the new maps through the legal system.  But the state Supreme Court rejected that effort late last month.
