LOS ANGELES (AP) — California's Sept. 14 recall election could remove first-term Democratic Gov. Gavin Newsom from office. Mail-in ballots, the form of voting most Californians use, already have arrived at voters’ homes.

The contest is unfolding as the state sees a surge in coronavirus cases from the delta variant and the return of masks and other mandates and restrictions in many places. There are raging wildfires in Northern California and an unrelenting homeless crisis.

Republicans are hoping for an upset in a heavily Democratic state, where the GOP hasn’t won a statewide election since 2006. The election is being closely watched nationally as a barometer of the public mood heading toward the 2022 elections, when a closely divided Congress again will be in play.

So, how did California arrive at this point? Here are some answers:

___

WHAT IS A RECALL ELECTION?

California is one of 20 states that have provisions to recall a sitting governor, 19 through elections. The state law establishing the rules goes back to 1911 and was intended to place more power directly in the hands of voters by allowing them to remove elected officials and repeal or pass laws by placing them on the ballot.

Recall attempts are common in the state, but they rarely get on the ballot and even fewer succeed. The only time a governor was recalled was 2003, when Democrat Gray Davis was removed and voters replaced him with Republican Arnold Schwarzenegger.

___

WHY IS THERE A RECALL DRIVE AGAINST NEWSOM?

The answer is simple and complicated.

The simple part: Californians grew angry during the pandemic. Whipsaw stay-at-home orders by Newsom, crushing job losses from business closures, shuttered schools and the disruption of daily life soured just about everybody. Many of life’s routines were cut off at some point if not altogether, whether trips to the beach or lunches at a favorite taco joint.

The complicated part: In a state with nearly 40 million people there are many grievances, including California’s wallet-sapping taxes, rising food and gas prices, the threat of water rationing to contend with a long-running drought and the continuing threat of wildfires. As governor, Newsom is a ready target for that resentment.

He is also being hit by fallout from a multibillion-dollar fraud scandal at the state unemployment agency while weathering a public shaming for going maskless while dining out with friends and lobbyists at an exclusive restaurant last fall, while telling residents to stay home for safety.

HOW DOES THE ELECTION WORK?

Voters are being asked if Newsom should be removed, yes or no, and then who should replace him. They will choose from a list of replacement candidates. If a majority of voters approve Newsom’s recall, the candidate who gets the most votes becomes governor. If Newsom is recalled, his replacement could be elected with just a fraction of the votes. With dozens of candidates dividing those ballots, it’s possible a winner could get 25% or less.

WHAT REPLACEMENT CANDIDATES HAVE ENTERED THE RACE?

There are 46 names on the certified ballot, though former Congressman Doug Ose withdrew this week after suffering a heart attack. The 24 Republican candidates include talk radio host Larry Elder, Kevin Faulconer, the former San Diego mayor; businessman John Cox, who was defeated by Newsom in 2018; Caitlyn Jenner, a reality TV personality and former Olympian; and Assemblyman Kevin Kiley.

There are nine Democrats, 10 independents, two Green Party members and one Libertarian. No Democrat with political stature decided to run — the best-known Democratic candidate is real estate agent and YouTube star Kevin Paffrath. Most of the candidates are largely unknown and have not mounted credible campaigns.

___

WHAT ARE CANDIDATES PROMISING?

Faulconer has proposed ending the state income tax for individuals making up to $50,000 and households up to $100,000 as part of a plan to make the state more affordable for the middle class. Cox sought to gain attention by campaigning with a 1,000-pound (450-kilogram) Kodiak bear, which he said represented the need for “beastly” changes in the state, and also is calling for a historic tax cut.

Elder has promised to bring a fresh eye and common sense to Democrat-dominated Sacramento, and has said he would swiftly lift state mask and vaccine mandates. Kiley has said he would immediately end the pandemic state of emergency, which would automatically wipe out all state and local orders issued under it.

WHAT IS NEWSOM SAYING ABOUT THE RECALL?

For months, Newsom steered around questions about a possible recall election, saying he wanted to focus on the coronavirus, vaccinations and reopening schools. But in March, he launched an aggressive campaign strategy, fundraising, running ads attacking the recall and doing national TV and cable interviews. He has acknowledged that people were anxious and weary after a difficult year dealing with the virus and restrictions.

Newsom, who was elected in a 2018 landslide, sees the recall as an attack on California’s progressive policies. Democrats say the effort to remove him is being driven by far-right extremists and supporters of former President Donald Trump. The recall is backed by state and national Republicans, but organizers argue they have a broad-based coalition, including many independents and Democrats.

The governor spent much of 2020 on the defensive. But he has benefitted from a record state budget surplus that allowed him to tour the state to announce vast new spending programs, including $12 billion to fight homelessness; checks up to $1,100 for millions of low and middle-income earners who struggled during lockdowns; and $2.7 billion to pay for all of the state’s 4-year-olds to go to kindergarten for free.

HOW PRECARIOUS IS NEWSOM’S HOLD ON HIS JOB?

In the depths of the pandemic, Newsom’s popularity was tumbling and he appeared imperiled, with widespread unrest over long-running school and business closures. Many business owners were infuriated by what they saw as Newsom’s heavy-handed restrictions that had some open and close several times. Others rebelled against mandatory mask-wearing rules.

Earlier this year, a reopened economy and the astounding windfall of tax dollars helped Newsom recover his standing. However, when Newsom fully reopened the state on June 15 virus cases were near record lows. Since then cases have been climbing, particularly among the unvaccinated.

Los Angeles County, which accounts for a quarter of the state's population, re-imposed a mandatory mask order on people who are indoors at public places, even if they’re vaccinated. California also is requiring K-12 students to wear masks when they go back to classrooms. Such an order could hurt Newsom, especially among those who felt he didn’t do enough to reopen schools last year.

Newsom himself has been warning the race is close, and Democrats fear many of their voters are shrugging at the contest while Republicans and conservatives are eager to vote.

Still, Newsom has an advantage over his GOP foes — California is one of the country's most heavily Democratic states. Democratic voters outnumber Republicans by nearly 2-to-1, and the party controls every statewide office and dominates the Legislature and congressional delegation.

Republicans last won a statewide election in 2006, when Schwarzenegger was reelected.
