Recently Supervisor Sean Elsbernd and his allies at the San Francisco Chronicle launched their repeal attempt of ranked choice voting (RCV) by declaring that “9 out of 11 of the members of the Board of Supervisors were not elected by a majority.” But Elsbernd twisted the truth, intentionally using funny math to make his case.
Here’s what I mean. When it comes to RCV they are comparing FINAL round vote totals to FIRST round vote totals – what is known as a “Whole Contest” comparison. But when it comes to their preferred December runoff system, they are NOT doing a “Whole Contest” comparison because they don’t compare final round vote totals (in December) to first round vote totals (in November). In other words, they are comparing apples to oranges.
But if we compare apples to apples, a different story emerges. Look at these two charts below, in which I compare RCV elections that elected the current Board of Supervisors to the last competitive December runoffs that elected those same districts. The results are illuminating.

That’s a lot of numbers to digest, but here’s what these numbers say, in a nutshell:
- With RCV elections, all current members of the Board of Supervisors were elected with a majority of “continuing ballots”(as indicated by the column called “Instant runoff percent”), which is how the San Francisco charter defines a winning majority;
- All current members of the Board of Supervisors were elected with an average of 43.2% of “whole contest” ballots. While that’s less than a majority, it’s WAY more than the “whole contest” winners elected by December runoffs, which averaged only 36.8%.
That’s because so many voters didn’t show up to vote in December – they are what I call “exhausted voters.” In fact, in ten of the city’s 14 December runoffs between 2000 and 2003, voter turnout declined by more than a third. So while races that elected the current Board of Supervisors had an average of 19.4% in “exhausted ballots,” the last competitive December runoffs in their districts had an average of 37.1% in “exhausted voters” – nearly twice as many!
In fact, when we compare all December runoffs to all “instant runoffs” that have been held, we find:
- In all the December runoffs, winners had 8,500 votes on average; but in all the instant runoff contests, winner’s on average won over 11,000 votes.
- December runoff winners’ had “whole contest” vote totals equivalent to 36% of the November vote total; but instant runoff winners’ had “whole contest” vote totals equivalent to 45% of first round vote totals, which is a huge increase.
- December runoffs had 38% exhausted voters on average; but instant runoffs had less than half that amount in exhausted ballots, only 17%.
In a nutshell, when comparing apples to apples, RCV elects winners with much higher vote totals, a higher “whole contest” vote total (percent of final round/election to the first round/election) and fewer exhausted voters/ballots than December runoffs.
That means with RCV, a LOT more San Franciscans are having a say in who their elected office holders are. In virtually every RCV race, candidates are winning with far more votes than they would have received in a low turnout December runoff, because with RCV we finish the election in November when voter turnout usually is highest. That means “instant runoff” winners have a MUCH GREATER VOTER MANDATE than December runoff winners.
The ultimate irony is that Sean Elsbernd himself is the poster child for what’s wrong with the old December runoffs and what’s right with RCV. Look at the results above for District 7: Supervisor Elsbernd won in 2004 in an “instant” runoff race with nearly 50% more votes than his predecessor Tony Hall had in 2000 in a delayed December runoff, 13,834 votes versus 9333 (in comparable turnout years). And Elsbernd had 43.7% of the “whole contest” vote total compared to 30.9% for Hall. No matter how you want to count it, more District 7 voters were able to have a say in who their supervisor is because Sup. Elsbernd was elected with ranked choice voting in a much higher turnout November election.
That’s what you call a mandate, Supervisor Elsbernd.

Supervisor Sean Elsbernd.
