Democratic U.S. Sen. Barbara Boxer of California has added her name to those opposing Proposition 11, a redistricting initiative.

A press release from the anti-11 group Citizens for Accountability quoted Boxer as saying in a letter to the group that she was concerned that the measure would put too much power in the hands of too few unaccountable people.

"And as you have pointed out, there are no guarantees that the commissioners will be representative of our diverse and dynamic state," Boxer wrote in the letter.

If approved, Proposition 11 would create a 14-member commission to redraw state legislative districts after the 2010 U.S. Census. The commission's members would be chosen by an independent panel of state auditors, and be comprised of Democrats, Republicans and non-affiliated citizens, all of them largely outside of party politics.

The commission would draw districts according to criteria that emphasized geographic continuity rather than voter makeup within a certain area. California congressional districts would be redrawn by legislators using the same criteria.

Proposition 11 is supported by Gov. Arnold Schwarzenegger, a Republican, and California Common Cause, a government reform advocacy group. Opposition has largely come from Democrats and some civil rights groups that fear redrawn districts could hurt representation of minorities in public office.

The pro-11 side has raised considerable amounts of money, including $75,000 in donations reported late Monday.

Citizens for Accountability has reported almost no money raised in comparison.
