Brown sold his Proposition 30 tax increase largely on the premise that it would stanch the budget bleeding — that it would end the painful school cuts and, he implied, halt the university tuition hikes.
He'd better hope that's what happens and that state revenues don't continue to fall short of spending. Because voters never like to be fooled.
From now on, it will be Brown's budget repair plan that is in place. No longer will he be able, with a straight face, to blame former Gov. Arnold Schwarzenegger and an intransigent Legislature.
Even more historic, Californians appear to have elected a Democratic two-thirds majority in each legislative house. It would be the first time in 80 years that one party has firmly controlled the entire apparatus of state government. Back then it was the GOP occupying the governor's office and holding supermajorities in both houses.
In the 1960s and '70s Democrats briefly controlled one house or the other with a supermajority. But they didn't hold absolute power. Now it seems they will. And history teaches us what absolute power can do: affix blinders and corrupt.
If this power is bestowed, the culpability at the Capitol will be entirely on Democrats. They'll be solely accountable, responsible for rerouting California back onto the right path. No finger-pointing at Republicans.
With a two-thirds vote, there's virtually nothing that can't be done in Sacramento. You can raise taxes, override a governor's veto, write constitutional amendments, propose bond issues. Budgets already can be passed on a simple majority vote because of a ballot measure approved two years ago.
But a legislative veer to the left — for yet higher taxation, more union pandering, denser business regulation — would probably propel voters back toward the right and California's traditional center.
Fortunately for Democrats and California, the same new system of reforms — a "top-two" open primary and independently drawn, competitive legislative districts — that enabled the majority party to make such dramatic gains also may keep it in check. Newly elected legislators who wander off to the left risk being yanked back home by the voters.
Brown dodged a potentially lethal bullet he himself fired that ricocheted.
When the nation's framers wrote the Constitution, they designed a republican form of democracy in which public policy was supposed to be decided by elected representatives. But in a 2010 campaign stunt, Brown promised voters "no new taxes unless you, the people, vote for them."
Brown thus surrendered much of his power. And in asking for the voters' approval to raise taxes, he broke a rule any trial lawyer learns early: Don't ask a question unless you already know the answer.
But the wily old pol pulled it off, despite being criticized by many — myself included — for offering mixed, often disingenuous messages.
Brown did it his way, the risky way, the agonizing way — if not the way the framers would have wanted. But it was the winning way and, in the end, surprisingly, not even close.
Prop. 30 passed by roughly 8 percentage points.
"It's a huge victory — underline huge — for Jerry Brown," says former Republican legislative leader Jim Brulte, a government affairs consultant.
"In a state that had rejected the last eight tax increases on the ballot, Gov. Brown got the voters to support taxes even in difficult economic times.
"I don't think you can underestimate the benefits to Jerry Brown of 30 passing. It means he'll be dealing with much smaller budget problems in the next two years. And it will quiet the liberal Democratic base that has seen nothing but budget cuts during his first two years in office."
It also means this: Brown will be much stronger, with a taller presence, than the weak governor he would have been had Prop. 30 failed. He'll be capable of exerting tons more power, a leader who must be dealt with —especially by business, which will have even less reason to work with irrelevant Republicans.
