From the new report:

Proposition 11, which would give a commission of registered voters the authority to determine state legislative districts, has split California’s likely voters as well (39% yes, 36% no, 25% undecided). Republicans (47%) are somewhat more likely than independents (39%) and far more likely than Democrats (31%) to support the measure, which is championed by Governor Arnold Schwarzenegger. In 2005, a measure that would have turned redistricting over to a panel of retired judges was trounced (40% yes, 60% no).
Likely voters’ apparent lack of support for Proposition 11 does not indicate satisfaction with the current system: Seven in 10 say the redistricting process needs major (42%) or minor (27%) changes, and more than half (56%) say state legislators would more effectively represent their districts if an independent commission of citizens redrew district lines.
