The San Francisco Chronicle is reporting that former state Senator Mark Leno is expected to concede the mayor's race to Breed at a news conference Wednesday afternoon. The city will release the latest election results at 4 p.m. PT.

The city's mayoral race was unresolved for a full week after election day, as votes cast for Breed and Leno were too close to call the race. Leno enjoyed a brief lead, but was soon overtaken by Breed as ballots came in.

San Francisco uses ranked-choice voting for local elections, which means residents marked their first, second, and third picks for mayor on the ballot last Tuesday.

While Breed received far and away the most first-choice votes (nearly 12 percentage points over Leno and 13 over Supervisor Jane Kim), Leno held a slight lead after election night because of the number of second- and third-choice votes cast in his favor.

As of Wednesday morning, Breed has pulled ahead of Leno with a 1,861-vote advantage. There are about 9,360 votes still be counted, according to the Chronicle.

Breed was known for attracting support from some recognizable names in tech: Gayle Conway, the wife of famed investor Ron Conway, reportedly gave $200,500 to a super PAC supporting Breed; Twitter cofounder Ev Williams is said to have similarly given 100,000 to two Breed-supporting super PACs.
