In fact, in the past 10 years, Los Angeles County alone has held 20 special elections to fill seats left vacant by resignation or death. The total price tag: tens of millions of dollars for polling places, voter guides -- all the machinery of an election has to be cranked up even if there's just one thing on the ballot.
"It makes things more complex, that's for sure," said L.A, County's elections chief, Dean Logan. He's hoping the three elections can all be held on the same date, April 3, when the election to fill Bocanegra's seat is already scheduled.
"That would help with overhead," Logan said, saying it costs "on average $1 million-$1.2 million to hold voting to fill each vacancy." While all three seats are in Los Angeles County, Logan notes the districts do not overlap, so each will require its own voting procedures, ballots and equipment.
Speaking diplomatically, Logan said the growing number of special elections "takes time away from new projects and voting innovations," such as a brand-new voting system the county is developing for the 2020 election. "It pulls resources away from that," Logan said.
And one resignation often sets off a series of others. For example, when Attorney General Kamala Harris was elected to the U.S. Senate, Gov. Brown picked Los Angeles congressman Xavier Becerra to replace her. A special election was called to fill Becerra's seat, and after a special primary and general election, the winner was Assemblyman Jimmy Gomez. He in turn had to resign to fill out the remainder of Becerra's term.
That required yet another special election (primary and general) to fill Gomez's seat in L.A. County. The primary was held Oct. 3, followed by a Dec. 5 runoff.
Kim Alexander, president of the California Voter Foundation, said it's an unexpected cost that local government has to eat.
"There had been a law in place in the past that would have reimbursed counties for special election costs, but it sunset," Alexander said, adding the law was never renewed by the Legislature.
In addition to the high cost, Alexander said, voters don't like to be bothered.
"A lot of times people feel like there's too many elections going on," she said.
The result of these oddly timed elections is often lack of interest, with turnout as low as just 8 percent of registered voters. The turnout for that Dec. 5 runoff in L.A. was just over 9 percent.
Election officials have tried and failed to get the state to cover the cost of unexpected special elections. But Santa Cruz County election chief Gail Pellerin isn't optimistic.
"There's just no money," Pellerin noted. "And especially now that the state budget is impacted with all the emergency fires. Who knows when elections will ever get paid?"
A constitutional amendment that would have avoided special elections by giving the governor the authority to appoint a successor to fill out the remainder of a term died two years ago -- it needed a two-thirds vote to put it on the ballot, and Republicans worried that a Democratic governor would name people who were too liberal. There's talk that it could come up again in the new year.
