Democratic presidential candidate Hillary Clinton will stage a "Club44 block party" political rally and street festival Sept. 30 in downtown Oakland.

"(T)housands of residents from throughout the Bay Area will spend the afternoon with friends, co-workers, neighbors and family members in support of Hillary Clinton," said a news release from the New York senator's campaign.

"Club44" is the campaign's effort, launched this summer in Washington, D.C., to engage women to make history by electing Clinton as the nation's 44th president.

The event, scheduled from 4:30 to 6:30 p.m. on Clay Street between 12th and 14th streets — between the Ronald V. Dellums Federal Building and City Center — will includelive music, entertainment, food vendors, and other family activities for the whole family, the campaign said; local entertainers will perform at the event, but no specific names have been released yet.

Admission to the Oakland event is $20 per person; children under 18 enter free. Tickets are available online at http://www.hillaryclinton.com/Club44Oakland.

U.S. Sen. Barack Obama, D-Ill., who polls show to be among Clinton's chief rivals for the Democratic presidential nomination, staged a rally March 17 in downtown Oakland's Frank Ogawa Plaza; tickets to that event were free, and his campaign estimated the crowd at about 12,000.

A Public Policy Institute of California poll of 455 likely Democratic primary voters, conducted Sept. 4-11, found Clinton supported by 41 percent and Obama by 23 percent; 2004 vice presidential nominee John Edwards was supported by 14 percent, while New Mexico Gov. Bill Richardson and U.S. Rep. Dennis Kucinich, D-Ohio, tied at 3 percent. The poll had a five percentage point margin of error.
