SACRAMENTO (CBS / AP) — Gov. Jerry Brown is maintaining a big lead over Republican challenger Neel Kashkari in this year’s governor’s race.

A Public Policy Institute of California survey released Tuesday found the Democratic governor with a 54 percent to 33 percent edge over Kashkari, a former U.S. Treasury official and Goldman Sachs banker.

Brown has majority support from women and Latinos.

The institute also asked about several ballot propositions. It found likely voters supporting Proposition 1, the $7.5 billion water measure, by a 2-to-1 margin.

Proposition 45, which would allow the state insurance commissioner to review rate changes, had support of just 48 percent of those surveyed.

The survey of 916 likely voters was conducted by telephone from Sept. 8-15 and has a sampling error margin of plus or minus 4.9 percentage points.
