(CNN) - A new poll indicates that Democrat Jerry Brown has a 10-point lead over Republican Meg Whitman in California's gubernatorial battle.
According to a Field Poll released Thursday, 49 percent of likely voters in the Golden State say that they are supporting Brown with 39 percent backing Whitman and 12 percent undecided or backing another candidate.
The Field Poll's Thursday release comes just hours after a CNN/Time/Opinion Research Corporation survey indicated that Brown has a 51 to 44 percent lead over Whitman. Brown's seven point advantage is at the edge of the poll's sampling error.
Brown, the state's attorney general, served two terms as California governor in the late 1970's and early 1980's. Whitman, the former eBay CEO and a billionaire, has contributed more than $120 million of her own money on her bid for governor.
The Field Poll indicates Brown is shoring up his support among female voters, independents and Latinos. The CNN/Time survey had similar findings.
The winner in November succeeds term-limited moderate Republican Gov. Arnold Schwarzenegger.
The Field Poll was conducted October 14-26, with 1,501 registered voters in California, including 1,092 likely voters, questioned by telephone. The survey's sampling error for likely voters is plus or minus 3.2 percentage points.
The CNN/Time/Opinion Research Corporation poll was conducted October 20-26, with 1,527 adults in California questioned by telephone, including 1,329 registered voters and 888 likely voters. The survey's overall sampling error is plus or minus 2.5 percentage points, with a sampling error of plus or minus 3.5 percentage points for likely voters.
