LOS ANGELES (CBSLA.com/AP) — California U.S. Senate candidate Kamala Harris claimed one of two spots in the November runoff Tuesday, moving the state attorney general into a potentially historic election.

Harris had a wide lead in early returns. She was trailed by fellow Democrat Loretta Sanchez, a 10-term congresswoman from Orange County, who was holding steady in second place.

It’s possible voters could send two Democrats, both minority women, to the general election.

Under California’s unusual election rules, only two candidates advance — the top vote-getters.

If the two Democrats prevail, it would be the first time since voters started electing senators a century ago that Republicans have been absent from California’s general election ballot for the Senate. Before that, senators were appointed by the Legislature.

With 2.6 million votes tallied, Harris had just over 1 million votes, or 40 percent. Sanchez was at 16 percent, with about 430,000 votes. Harris was performing strongly in the San Francisco Bay Area, her stronghold, but was also leading in Democrat-rich Los Angeles County.

Republican candidates were lagging in single digits. Duf Sundheim, a Silicon Valley lawyer and a former chairman of the California Republican Party, was leading a cluster of Republicans trailing the two Democrats.

In a year when millions of voters embraced outsider candidates in the presidential contest, California Senate voters appeared impressed with the deep experience of the two Democrats.

Hoai Le, a 62-year-old mechanic from Santa Ana, said he was backing Sanchez because of her two decades in Congress.

“She’s been there for a while. She knows how the system works,” said Le, an independent, after casting his ballot at a community center. “She can do a lot better than the new guy.”

Jeanette Wright of San Francisco, a 47-year-old executive assistant with the state, said she was impressed with Harris, a career prosecutor.

“She’s a strong woman. She’s been around. She knows what’s going on with San Francisco. She knows what’s going on with the community,” Wright, a Democrat, said of the attorney general.

If elected this fall, Harris, the daughter of immigrants from India and Jamaica, would set historical marks. She would become the first Indian woman to hold a Senate seat and the second black woman elected to the Senate.
Illinois Sen. Carol Moseley Braun was elected in 1992 and served one term.

“We will continue to run a campaign that is about fighting for the ideals of our country, reminding folks of that great promise we articulated in 1776, that we are all and should be treated as equals,” said Harris in her victory speech Tuesday.

“It will be about reminding people that we reject those people who talk about us versus them. We reject those people who would try and divide us. We those people who speak this anti-immigrant, anti-Muslim rhetoric,” she said. “We reject all of that.”

Thirty-four candidates are seeking the Senate seat being vacated by retiring Sen. Barbara Boxer.

Sanchez, if elected, could become one of the first Latinas to hold a U.S. Senate seat. Catherine Cortez Masto, who is also Hispanic, is the Democratic candidate for outgoing Sen. Harry Reid’s seat in Nevada.

In claiming her victory, Sanchez thanked her supporters and her mother, who she credited with educating her and her six siblings.

“I know that the American dream is alive in America. And this is a story that all Americans and all Californians can agree on – Republicans, and Democrats, and Independents – the American dream,” Sanchez said. “That is what we all want.”

Sanchez said, though Harris has raised more money and is in the lead, she is confident in November that she’ll win.

The fact that both spots could be taken by Democrats reaffirms the party’s dominance in the nation’s most populous state.

California once was a reliable Republican state in presidential elections. But the party has seen its numbers erode for years, and it now accounts for a meager 27 percent of registered voters.

Democrats control every statewide office and both chambers of the Legislature, while holding a registration edge of nearly 2.8 million voters.

With 12 Republicans on the ballot — and none widely known to voters — the GOP vote was splintered Tuesday, weakening the party’s chances of advancing a candidate to November.

Still, a surprise is possible with a large field and polls showing many undecided voters.

As fellow Democrats, Harris and Sanchez hold similar positions on many issues, including abortion rights and immigration reform.

But a fall contest would create demographic and geographical contrasts for state voters: Sanchez is Hispanic with roots in Southern California, while Harris is from the San Francisco Bay Area, and her father is black and her mother Indian.

Harris, 51, a career prosecutor, has played up winning a big settlement with banks accused of improper mortgage foreclosures and her work to defend the state’s landmark climate change law.

Sanchez, 56, has stressed her national security credentials built up during 10 terms in Washington.
