Looks as though it will be Bass against Pratt in an LA showdown, but there's still time for the rulers to "adjust" the numbers as they count the mail-in ballots

I asked ChatGPD how this all works so that you don’t have to if, like me, you don’t understand how California’s primary system works — I didn’t ask Chat how California’s voters can habitually elect people like Karen Bass and Gavin Noisome, because artificial intelligence is not the same thing as no intelligence at all.

Q: As a non-resident interested in Los Angeles' mayoral race, I see that today's primary (June 2 2026) saw Karen Bass get (approx) 36% to Spencer Pratt's 29.5%. I'm unfamiliar with that state's election procedures; do the results mean that Bass has won, or only that she'll be in a runoff later this summer with Pratt?

A: No—those numbers do not mean Karen Bass has won outright.

Los Angeles uses California's "top-two" (sometimes called "jungle primary") system for mayoral elections. All candidates run on the same ballot, and:

  • If a candidate receives more than 50% of the vote, they win outright.

  • If no one reaches 50%, the top two finishers advance to a runoff/general election in November.

With Bass at roughly 36% and Pratt around 29.5%, neither is close to a majority, so the current result points toward a runoff rather than an immediate victory. Reuters reported Bass leading with about 36.6% and Pratt second with about 29.8%, which would place those two in the November contest if the standings hold as remaining ballots are counted.

One wrinkle: California counts mail ballots for days or even weeks after Election Day, so the exact ordering of second and third place can still shift when margins are close. Some reporting overnight noted that Bass had clearly advanced, while the battle for the second runoff spot between Pratt and Nithya Raman was still not mathematically settled.

So the practical takeaway is:

  • Bass has not won the mayoralty.

  • Bass appears very likely to have qualified for the November runoff.

  • Pratt is currently in position to join her in that runoff, but the final certification will determine the matchup.

For someone coming from states that hold separate partisan primaries, California's system can feel unusual because what happened on June 2 was effectively a first round of the mayoral election, not the final election. The decisive head-to-head contest would be in November unless someone had crossed the 50% threshold.
