LONGEST TERMS IN OFFICE
Since the introduction of term limits in 1990, State Executive and State Senate members can only hold an office for two four-year terms. For the State Assembly, the limit is three two-year terms. Seats in the US House of Representatives and US Senate are not bound by term limits, and members may serve as long as the voters in their districts reelect them. The current longest-serving member of the legislature is State Senator Tom McClintock (who is serving his 22nd year in the Assembly and Senate). Mervyn M. Dymally will have served 20 years when he terms out of the Assembly this year. He is currently a candidate for State Senate, which if elected, would allow him to extend his service to 28 years.
Before the introduction of term limits, officials were limited only by their ability to attract voters on Election Day. With his Assembly and State Senate service combined, Ralph C. Dills holds the record for longest tenure in the state legislature. The following is a list of the longest terms in office in California history.
