* Democrats want more choices for governor's race

* Likely Republican challengers lack wide appeal so far

* Voters disillusioned with leaders, state's future

LOS ANGELES, Nov 8 (Reuters) - California Attorney General Jerry Brown is by far the most popular candidate for governor in next year's election, but most voters in his party are unhappy that he is the only major Democrat running, according to a new poll on Sunday.

Sixty-five percent of Democrats surveyed in the Los Angeles Times/University of Southern California poll said they wanted additional Democratic Party options now that San Francisco Mayor Gavin Newsom had quit the race on Oct. 30.

Fewer than a third were satisfied with Brown -- a former two-term governor, onetime Oakland mayor and three-time Democratic presidential hopeful -- as the only choice.

The withdrawal of Newsom, known nationally for his fight to legalize gay marriage but lagging in recent polls, left Brown as the only major politician seeking the Democratic nomination next year to succeed Arnold Schwarzenegger as governor.

Although he has yet to formally declare his candidacy, Brown drew the most favorable ratings in the gubernatorial field, 44 percent, not unsurprising in a state long known for its Democratic leanings as a whole.
