A powerful pro-Israel advocacy group and its allies have spent more than $5 million in recent weeks to try to influence a special election in California's East Bay area. The race is to fill a congressional seat left empty when Eric Swalwell resigned earlier in 2026.

Here is what makes this unusual: the candidate being targeted, Aisha Wahab, is already far ahead in the race. She leads her closest competitor by more than 20 percentage points. So the money is going toward trying to close a very large gap in a short amount of time.

The group behind much of the spending is AIPAC, which stands for the American Israel Public Affairs Committee. It is the largest pro-Israel lobbying organization in the United States, meaning it works to influence lawmakers to support policies friendly to Israel.

AIPAC does this in part through super PACs. A super PAC is a type of political group that can raise and spend unlimited amounts of money to support or oppose candidates, as long as it does not work directly with the candidate's own campaign. Think of it as a bystander who can spend as much as they want on billboards and ads for or against someone, but is not allowed to walk into the campaign office and coordinate.

The spending includes $1.2 million from United Democracy Project, an AIPAC-backed super PAC, which disclosed $800,000 in direct spending on the race, according to Politico. Bold America PAC, which has received significant financial backing from United Democracy Project, contributed $2.1 million. Track AIPAC, a group that monitors AIPAC's spending, reported that AIPAC's total spending in support of Hernandez exceeded $4.4 million. The outside money has funded advertising in favor of Hernandez and attack ads against Wahab. Outside groups had spent a combined $2.45 million in the race as of August 5, per the American Prospect, a figure that has since climbed as additional spending was reported.

Wahab is a California state senator endorsed by the California Democratic Party, and she is widely considered the frontrunner. She outpaced her closest competitor, former Dublin mayor Melissa Hernandez, by more than 20 points in both the June primary and the special election to complete the remainder of Swalwell's term, according to the Guardian. The Associated Press had separately confirmed Wahab's advancement to the special general election in June. The two candidates are set to face off in a runoff election later in August 2026 and again in November.

Wahab has criticized Hernandez for allegedly dodging debates while relying on outside money. "We're not going to let this race be bought by outside interests," Wahab said in a social media video.

FEC records list a committee named "Melissa Hernandez for Congress" (committee ID C00932541), registered on January 1, 2026, as an independent expenditure-only committee. This means the committee can spend money on its own to support or oppose a candidate, but cannot give money directly to that candidate's campaign.

This is not a one-time effort. The New York Times reported that AIPAC doubled its political spending to $67.2 million, concentrated largely in Democratic primaries. In Michigan's Democratic Senate primary, AIPAC spent millions backing moderate candidate Haley Stevens against progressive Abdul El-Sayed. El-Sayed won the contest anyway.

The broader context here is that AIPAC has been steadily increasing its role in American elections over the past several years. The organization has poured significant resources into Democratic-leaning areas to support moderate candidates over progressives who have the backing of state party leadership. What stands out about the East Bay race is the amount of money relative to the contest: more than $5 million in super PAC spending for a single House special election is a large sum, especially when the candidate being targeted already holds a 20-point lead.

The real question is whether spending at this level can actually close a 20-point gap in a short runoff period, or whether it mainly serves as a signal that AIPAC is willing to spend heavily even in races where the outcome looks decided. Michigan offers one example where heavy spending did not change the result. But every race is different, and the August runoff and November general election will show whether the investment narrows Wahab's lead or shifts the race.
