Aisha Wahab will be replacing Swalwell until the November election, due to the results of a special election to determine the disgraced Swalwell’s successor. As you can probably tell from the name, Wahab is the US-born child of Muslim immigrants (in her case, her parents are from Afghanistan) and a DSA-supported candidate:

Far-left Afghan American California state Sen. Aisha Wahab (D) defeated establishment-backed Democrat candidate and Bay Area Rapid Transit Board member Melissa Hernandez, 53.1% to 46.9%. …

The result was far closer than expected. Wahab and Hernandez were the top two finishers in the June special primary, with Wahab taking 42.8% of the vote to Hernandez’s 16.8%.

Once again, we have a low-turnout primary in which the more extreme candidate won, and then in the election itself – featuring two Democrats, because they were the two top vote-getters – the more extreme candidate won but not by as much (then again, a runoff eliminates the rest of the vote-getting opposition compared to the primary). In this case, the more “establishment” wing of the Democrat Party tried to stop Wahab but could not:

Millions poured into the race from AIPAC and other political action committees determined to keep another radical candidate from winning a seat in Congress.

They failed.

There’s a general election in November. It’s a kind of do-over, with Republican voters will be added to the mix – not that there are so many in California’s District 14. But there will be more voters, period, and Wahab may lose her seat to Hernandez in November. There will be no Republican opponent because of the aforementioned primary rules in California.
