Georgia congressional candidate Jon Ossoff, who’s turned his special election race next week into a referendum on President Donald Trump, reported receiving almost as much money from the Bay Area than from the entire state of Georgia over the last two months.

He also reported receiving almost nine times as many individual donations from California than from Georgia, according to federal campaign finance data released last week.

In total, his campaign raked in $15 million from March 29 to May 31, for a total of over $23 million — a haul that has made this the most expensive House race in U.S. history.

The 30-year-old candidate, a documentary filmmaker with no experience in elected office, is running against Republican Karen Handel, a former secretary of state in Georgia. She has raised just $4 million.

In the April special election, Ossoff got 48.1 percent of the vote, compared to 19.8 percent for Handel, who was one of several Republicans in the race. Because no candidate got 50 percent, the two went on to a runoff election, which will be held on Tuesday. Recent polls have shown the rivals neck and neck.

But in money raised, Ossoff has blown Handel out of the water — thanks in part to the Golden State.

Between March 29 and May 31, Ossoff reported receiving 7,218 donations from California, dwarfing the 808 donations he received from Georgia. In the nine Bay Area counties alone, he received 3,063 donations in the same time period.

Those are only a fraction of Ossoff’s total donations, as he doesn’t have to report contributions from people who give less than $200 in total. In addition, many of the individual donations include the same people giving to his campaign multiple times.

Overall, he reported receiving $456,296.03 from California — and $220,532.10 from the Bay Area — versus just $228,474.44 from Georgia.

That’s an even larger disparity than from his earlier donations report in April, which showed him receiving more donations from the Bay Area and California than from Georgia, but raising more funds overall in his home state.

A Bay Area News Group story about those figures fueled misleading Republican attack ads on Ossoff portraying stereotypical San Franciscans talking about how much they loved the candidate.

Ossoff has toed the line between running a campaign opposing Trump and focusing on local issues in his district, which covers a swath of the affluent northern Atlanta suburbs. While he launched his campaign describing himself as “Trump’s worst nightmare,” more lately he’s tried to paint his approach in an almost nonpartisan light.

But for out of state donors, the idea of sticking one to Trump with an Ossoff win is the big draw.

Rosaria Haugland, 77, a philanthropist and former scientist in Palo Alto, gave Ossoff $2,167 in a series of small donations. She said she didn’t know much about Ossoff, other than that he would fight Trump — and that was enough for her.

“It’s the only thing that I can do,” she said. “I don’t care if the person who becomes president is Democrat or Republican. I care if it’s a person you can trust. The only way that can help is if the Democrats start getting more power.”

Some of Ossoff’s more notable Bay Area donors include Charlie Cheever, the co-founder of tech company Quora, who gave $2,200; Laszlo Bock, a former Google executive, who gave $2,700; and Justin Faggioli, a Marin County entrepreneur and the former mayor of Belvedere, who gave $2,700.
