Mena is running for the open State Senate seat in District 29 after veteran Sen. Steve Conway announced his retirement following 34 years in the legislature. Fellow Rep. Melanie Morgan (D-Spanaway) has endorsed her bid. If elected, Mena would bring her environmental justice and working-family advocacy from the House to the Senate.
Conway, 81, served 18 years in the House before winning the Senate seat in 2010. Mena declared candidacy for the State Senate primary and withdrew from her House re-election race. She won her 2024 House race with 93.8% of the vote (write-in opposition only) and originally won the seat in 2022 with 58.4%. No other candidates have publicly declared as of early 2026.
Key dates to watch: Primary on August 4, 2026 and General Election on November 3, 2026.
