American politics will never be perfectly clean because politicians represent and reflect imperfect humans. Yet voters unreasonably expect the people they elect to be, on the whole, better than themselves.

It’s actually more of a hope — even a demand — than an expectation. Citizens have become accustomed to expect the worst because of scandal after scandal.

In a recent poll by the Public Policy Institute of California, adults were asked whether they thought the state government was “run by a few big interests looking out for themselves” or was “run for the benefit of all of the people.”

No surprise: 67% answered “big interests.” Only 31% replied “the people.”

Although predictable, that’s disappointing and sad.

Most politicians I’ve been around over the decades have been relatively ethical — just as most voters who elect them are basically honest. Voters tend to elect people with similar values.

But there are always some rotten apples. That’s nature.

It’s also human nature — certainly in America — to strive toward perfection even when we know that reaching that goal is impossible, at least for more than a short period.

Therefore, legislation has been introduced in Sacramento that could reduce the influence of special interest money in politics.

It would allow California governments — the state, counties and all cities — to enact some form of public financing of election campaigns.

Look, running for office costs barrels of money, especially in California. The money must come from somewhere. And as I’ve written many times, either the public buys the politicians or the special interests eagerly will — and often do.

In California, some cities are allowed to set up public financing systems but others, illogically, are not. Neither are counties or the state.

Los Angeles city operates a public financing system. Public funds match private contributions.

For every $1 up to a certain amount that a city resident donates to a council or citywide candidate, taxpayers kick in $6. But candidates receiving public funds must agree to campaign spending limits.

LA spent roughly $12.8 million on matching funds for the 2022 elections.

San Francisco has a similar system.

But Oakland has a different partial public funding method: Each registered voter receives four $25 “Democracy Dollars” they can donate to qualified city candidates.

Long Beach and Berkeley also have public funding systems.

Those five entities are allowed to because they’re so-called charter cities. By an odd quirk, general law cities — there are 357 of them — are not permitted to enact public financing for campaigns.

That happened because of the 1974 Political Reform Act, a ballot measure sponsored by young Secretary of State Jerry Brown, who was running for governor on a post-Watergate platform of “clean up Sacramento.”

Brown’s measure required more substantive public disclosure of campaign contributions and spending. But he was afraid opponents would attack it as a scheme to spend tax dollars on politicians. So he wrote into the initiative the current restriction on public financing.

“We were worried Republicans would say ‘no to public financing,’ use that against us in the campaign and it wouldn’t pass,” recalls Bob Stern, who helped Brown write the act and is a longtime political reformer.

The measure passed overwhelmingly.

In 2016, the Legislature passed and then-Gov. Brown signed a bill to remove the ban. But the courts ruled the question must go to the voters because of the way Brown wrote the 1974 act.

That’s what the current legislation would do — send the question back to the voters in November 2024.

Two identical bills — SB 24 and AB 270 — have been introduced by veteran state Sen. Tom Umberg, D-Santa Ana, and Assemblyman Alex Lee, D-San Jose.

Umberg says he’s not particularly sold on public financing but wants to allow local entities to experiment with it if they choose.

“I’ve been trying to figure out a way to reduce the influence of money in politics,” he says, “and I haven’t figured it out. I’d be interested in seeing what local communities would do.

“States are called laboratories of democracy. Cities and counties could be laboratories of addressing the influence of money in politics.”

Sen. Ben Allen, D-Santa Monica, who authored the 2016 bill, says: “This is a ‘let 1,000 flowers bloom’ issue.”

“The cost of campaigns is increasingly out of control. It puts so much power in the hands of the wealthy and special interests. I don’t see (public financing) as a magic bullet. But it can make our campaigns cleaner.”
