Democrats were hopeful of regaining their two-thirds majority in the state Senate, based on partial returns in a pair of special elections Tuesday.
They were on track to keep their narrow supermajority in the Assembly at least until mid-May, when another seat is likely to go vacant in a merry-go-round of special elections.
Assemblyman Ben Hueso, a Democrat from San Diego, was leading with 51 percent of the vote, with about a third of precincts reporting, in a four-way race in the 40th Senate District.
If his share remains above 50 percent, he will avoid a runoff election and once again give Senate Democrats the 27 votes they need to raise taxes, pass emergency legislation, override gubernatorial vetoes and put constitutional amendments before voters.
Voters set up a May 14 runoff in the 32nd Senate District, although Democratic Assemblywoman Norma Torres of Pomona remains the favored candidate.
With all precincts reporting, Torres led with 44 percent of the vote in a six-candidate field. She will face Ontario Mayor Paul Leon, a well-financed Republican, in a contest between the top-two vote-getters from Tuesday's primary. Leon trailed with 26 percent of the vote.
Democrats make up nearly half the voters in both districts, with about 28 percent registered Republican and a fifth of voters having no party preference.
Tuesday's primaries for the two open state Senate seats carry consequences that could be more significant than in a typical legislative race.
Democrats won two-thirds majorities in both houses of the Legislature last fall, but there is a chance at least one chamber may lack a supermajority for the rest of the year. The uncertainty is caused by three open Senate seats — and possibly a fourth — and the musical chairs among Assembly members.
If both current Assembly members win, either Tuesday or in May, Assembly Democrats will be temporarily short of the 54 seats they need for a supermajority. Moreover, they will lose Assemblyman Bob Blumenfield, D-Sherman Oaks, in July, when he leaves to join the Los Angeles City Council.
Assembly Democrats are unlikely to regain their supermajority until shortly before the Legislature adjourns in mid-September. Depending on the outcome and timing of special elections, they could lack their full two-thirds until early next year.
"It's an opportunity for the taxpayers to breathe a little bit easier for a couple of months," said Assembly Minority Leader Connie Conway, R-Tulare. "I think it makes a tremendous difference, in as much as even if they get there eventually, for right now we're able to hold them off."
The game of musical chairs merely postpones the inevitable, said Steve Maviglio, a spokesman for Assembly Speaker John Perez, D-Los Angeles.
"They're all Democratic seats. There's no risk. It's just a matter of when," he said.
Tuesday's election is to fill the seats vacated when Democratic Sens. Gloria Negrete McLeod of Chino and Juan Vargas of San Diego resigned to take seats in Congress, which they won last fall.
Senate Democrats also have a surprise vacancy created when Sen. Michael Rubio, D-Bakersfield, resigned last month to take a job with Chevron. The special election in the Central Valley's 16th Senate District will be May 21, with a special runoff election on July 23 if no candidate wins a majority in the primary election.
They also could lose Sen. Curren Price, D-Los Angeles, in July if he wins a May 21 runoff election for a Los Angeles City Council seat.
Senate Minority Leader Bob Huff, R-Diamond Bar, said Republicans also hope they can field a strong candidate to replace Rubio. Although about half the district's voters are Democrats, he said they have generally favored more limited government.
But he and Senate President Pro Tem Darrell Steinberg, D-Sacramento, agreed that Senate Democrats will regain their supermajority soon enough to advance any bills or constitutional amendments they choose.
Perez said the possible loss of the Democrats' supermajority in the Assembly will not affect his emphasis on working with Republicans to improve the state's economy and creating jobs.
"Obtaining the supermajority didn't change the world; temporarily losing the supermajority won't change the world," Perez said in a statement. "With or without the supermajority, I will continue to seek bipartisan support for major legislation."
Allan Hoffenblum, publisher of the California Target Book, which analyzes legislative and congressional campaigns, said the Assembly includes relatively conservative Democrats who will face tough re-election fights and are unlikely to support raising taxes.
"The supermajority was more of a psychological boost more than anything," he said. "It's more a reflection of how weak Republicans are in the state."
Democrats in both chambers will regain their two-thirds margins this fall or early next year, Hoffenblum said, just in time for next year's campaigns to begin.
