There’s no clear leader in the California Republican primary for governor and nearly half of registered GOP voters are unsure about whom they support, according to a Field Poll conducted Sept. 18 to Oct 5.

Former Ebay CEO Meg Whitman leads in a three-way match-up with 22 percent of the vote, former five-term Rep. Tom Campbell earns 20 percent and state Insurance Commissioner Steve Poizner comes in at 9 percent. Another 49 percent of Republicans said they were undecided. The margin of error was 4.5 percent.

All three remain unknown to the majority of California voters - 68 percent have no opinion of Whitman, 61 percent no opinion of Poizner and 59 percent no opinion of Campbell.

The prospective Democratic candidates are much better known to the electorate - approximately 60 percent of voters had an opinion of Attorney General Jerry Brown or San Francisco Mayor Gavin Newsom.

California Attorney General Jerry Brown is outpolling his likely opponents for the Democratic gubernatorial nomination and for the 2010 general election, according to a Rasmussen Reports survey taken Sept. 24.

Brown, who served two terms as governor in the 1970s, has a higher favorability rating than San Francisco Mayor Gavin Newsom, who also is seeking the Democratic nomination, 53 percent to 45 percent.

And in a hypothetical general election race, Brown leads former eBay CEO Meg Whitman, a Republican candidate, 44 percent to 35 percent, and two other candidates now seeking the Republican nomination, state Insurance Commissioner Steve Poizner 45 percent to 32 percent, and former U.S. Rep. Tom Campbell 44 percent to 34 percent, according to Rasmussen.

A Research 2000/Daily Kos poll of 600 likely voters conducted Aug. 9-12 shows Republican Meg Whitman, the former CEO of eBay, and Democrat Jerry Brown, the current state attorney general and a former governor, leading their respective fields for the open 2010 governor's race in California.

In a hypothetical general election matchup between the two, Brown bested Whitman 42 percent to 36 percent, with 22 percent undecided.

Brown also led San Francisco Mayor Gavin Newsom in a hypothetical Democratic primary matchup, 29 percent to 20 percent -- but a whopping 51 percent said they were undecided.

On the Republican side, Whitman led former Rep. Tom Campbell and state Insurance Commissioner Steve Poizner in the GOP primary: 24 percent for Whitman, 19 percent for Campbell, 9 percent for Poizner and 48 percent undecided.

California Sen. Dianne Feinstein would be the clear favorite in a Democratic primary for governor in 2010 if she chooses to make the run according to a Field poll conducted Feb. 20 - March 1.

Attorney General Jerry Brown and Los Angeles Mayor Antonio Villaraigosa tie for second at 16 percent and San Francisco Mayor Gavin Newsom registers 10 percent. All others are in single digits.

Should Feinstein not run, Brown would be out front by 26 percent followed by Villaraigosa at 22 percent, Newsom at 16 percent and Lt. Gov. John Garamendi at 8 percent.

SurveyUSA tested the appeal of a slate of potential or announced candidates for California's governorship in 2010 and didn't find any of them firing up voters with enthusiasm, but the poll did not include two big names, Los Angeles Mayor Antonio Villaraigosa and Sen. Dianne Feinstein.

The survey asked voters to rate seven people on a scale of one to 10 with "10" meaning the individual had the "highest qualifications" and "1" signifying "completely unqualified."

The only name to garner a double-digit response in the "10" category was Attorney General and former Governor Jerry Brown who also had the highest favorability rating at 31 percent. However, only 10 percent graded Brown as a "10" compared to 20 percent who considered him completely unqualified, and those that viewed him unfavorably, at 34 percent, exceeded his favorable numbers.
