The man at the front of the line has a beard and a belly, and he looks nothing like a Hollywood starlet. He steps up to the table and gives his name: Sydney Sweeney.

The poll worker starts to ask for his ID, and her supervisor stops her because she isn't allowed to ask.

So she hands him a ballot. He tosses his hair and walks off with three "I voted" stickers on his shirt.

Later, an AI-generated version of the real Sydney Sweeney shows up to vote, and she's the one with a problem.

"This ad is a parody," the closing card reads, "but the problem is not."

The ad comes from Californians for Voter ID, the campaign behind Proposition 39, and it may be the most effective piece of election-integrity messaging of the year. Sen. Mike Lee shared it with a simple caption: "'Sydney Sweeney' makes the case for Voter ID." Elon Musk reposted it, and within a day it had hundreds of thousands of views.

The campaign's pitch is blunt: "California is one of a handful of states that don't require a photo ID to vote."

The ad works because it isn't much of an exaggeration. California's own Secretary of State says voters generally don't have to show ID at the polls. When you register, you check a box swearing that you're a U.S. citizen, and nobody asks for proof. After that, you can walk into a polling place, give a name, and get a ballot.

Proposition 39 would change that. It's a constitutional amendment, placed on the ballot after supporters gathered more than 1.3 million signatures. It would require a government-issued ID to vote in person, and the last four digits of an ID number on every mail-in ballot envelope. It would require election officials to use government data to make their "best efforts" to confirm that registered voters are citizens, and to report each year what percentage they've verified.

And it would require the state to provide a free ID card to any voter who doesn't have one.

That provision takes the air out of the opposition's main argument. The California Democratic Party, Sen. Alex Padilla, and the state's labor federation all oppose Prop 39, warning it will keep eligible voters from the polls. But it's hard to argue a free ID card disenfranchises anyone, in a state where you already need ID to board a plane, open a bank account, or buy cold medicine.

Most Americans don't find the idea controversial. Gallup has found that 84% of Americans support requiring photo ID to vote.

California's political class is the exception. When the voters of Huntington Beach approved voter ID for their own city elections in 2024, Sacramento responded by passing a law banning any city in the state from requiring it.

The ad lands in a week when the issue is anything but theoretical. Federal agencies have flagged more than 20,000 suspected noncitizens on California's voter rolls who were mailed ballots this fall. On Monday, the Justice Department charged 28 people from that list with fraudulently registering to vote, and officials say most of them cast illegal ballots.

None of them needed to look like Sydney Sweeney, because nobody checked who they were.

There's one more irony. California's lawmakers tried in 2024 to outlaw AI-generated election ads like this one, and a federal judge blocked the law on free speech grounds. So the deepfake Sydney Sweeney is perfectly legal, while asking for ID at a polling place is effectively banned.

California asks for your ID to buy Sudafed, and Prop 39 would ask for it when you vote. Voters will decide on November 3 whether the man in the ad, or anyone else, can walk up to a table, give any name he likes, and walk away with a ballot.
