The only real election drama is if
With a supermajority, a political party can raise taxes, place measures on the statewide ballot, enact laws immediately with an "urgency" clause and override a governor's veto. In theory, it's an enormous amount of power.
Democrats grabbed two-thirds of all legislative seats in 2012 — the first time any political party had done so in both houses since 1933 — aided by newly drawn political maps and President Obama's romp over Mitt Romney.
Republicans erased that Democratic supermajority in 2014 by throwing everything they had into legislative elections. And they're trying to hang on this year.
"They're fighting to stay alive," said Darry Sragow, publisher of the nonpartisan Target Book that handicaps state politics. "They're fighting to stay relevant."
Democrats can reclaim their Assembly supermajority by winning two of the four seats they lost in 2014. These closely watched races in communities surrounding Torrance, Santa Ana, Palmdale and the suburbs east of San Francisco are attracting millions of dollars in campaign cash.
Big money is also at play in an effort to oust a Republican assemblyman near San Bernardino. Democrats would also love to steal an Assembly seat near Corona that's in the GOP column.
"The Republicans are in this very difficult, unenviable position," Sragow said.
In the Senate, the path looks more narrow even though Democrats only need to pick up a single seat. Contested districts in the Antelope Valley and northeast Orange County have usually been won by Republicans.
Sragow said he believes that GOP voters won't abandon down-ticket races, even in this difficult presidential season and with 16% of voters saying they don't plan to vote in the U.S. Senate contest between two Democrats.
"If political insiders are assuming that, because of Donald Trump's unpopularity in California, fewer Republicans are going to turn out and vote, that assumption would be a huge mistake," he said.
Still, let's play out the "what if" game: What could Democrats do with a supermajority of seats in the Legislature?
In truth, it's probably more bragging rights than brawn.
Business groups that used to spend campaign cash electing Republicans now work to elect kindred souls who happen to be Democrats. That's made the majority party, especially in the Assembly, a lot more heterogeneous.
Recent battles, from climate change policies to workplace rules, have proved how fractious Democratic politics can be.
And there's still the governor to stop liberal-leaning tendencies. A former leader of Assembly Republicans once famously called Gov. Jerry Brown "the adult in the room" when it comes to saying no.
The more perilous question for Republicans is what happens in 2018 and beyond. Under the term-limits law revamped by voters four years ago, newly elected legislators can serve up to 12 years. That means even Democrats who don't agree on everything would be in a position to act unilaterally should they agree to close ranks.
