Votes have all been counted in the California March 5, 2024 primary in San Mateo and Santa Clara Counties, so it is now possible to know that there is a tie for second place in the U.S. House race, 16th district. No incumbent was running. Nine Democrats and two Republicans appeared on the primary ballot. Democrat Sam Licardo, a county supervisor, placed first with 38,489 votes. Evan Low, an Assemblymember, and Joe Simitian, a former Mayor of San Jose, each got 30,249 votes. They are also both Democrats. So three Democrats will be on the November ballot.
This is the second time the California top-two system has produced a tie for second place, with the result that three candidates qualified for November. The first instance was in 2016, in the 62nd Assembly race, when only a Democrat had appeared on the primary ballot, and two write-in candidates (a Republican and a Libertarian) had been write-in candidates in the primary and each got 32 write-in votes, so all three went into the November election.
In theory, in the current race, one of the candidates could ask for a recount, but that is not expected to happen, because whoever requested the recount would need to spend a lot of money on the recount.
