WASHINGTON (AP) - The Supreme Court is being asked to let raw politics play an even bigger role in the drawing of congressional district boundaries.
The court hears argument Monday in an appeal by Republican lawmakers in Arizona against the state's voter-approved independent redistricting commission for creating the districts of U.S. House members.
A decision striking down the commission probably would doom a similar system in California, and could affect districting commissions in 11 other states.
The court previously has closed the door to lawsuits challenging excessive partisanship in redistricting - or gerrymandering.
The Obama administration says independent commissions such as Arizona's "may be the only meaningful check" left to states that want to foster more competitive elections.
