SACRAMENTO — A new poll shows Gov. Arnold Schwarzenegger's popularity dropping, but most voters don't support a prison guard union's attempt to recall him.

The Field Poll released Tuesday finds that 69 percent of California voters oppose recalling the governor.

Twenty-nine percent support the recall effort by the state prison guards' union if it qualifies for a special election ballot.

The poll also found that just 38 percent of respondents approved of Schwarzenegger's job performance.

The California Correctional Peace Officers Association last week filed a formal notice with the secretary of state seeking to start a recall drive against Schwarzenegger.

The telephone interview of 1,008 registered voters was conducted Sept. 5-14. It has a margin of sampling error of plus or minus 3.2 percentage points.
