Biography

Darrin Camilleri is a Democratic state senator from Michigan who represents District 4 and is seeking re-election in the November 3, 2026 general election.[1][2] A former social studies teacher, he served three terms in the Michigan House before joining the Senate in 2023.[1]

Darrin Camilleri was born in Brownstown Township, Michigan, and lives in Trenton.[1] He graduated from Gabriel Richard Catholic High School in 2010 and earned a B.A. in political science and government from Kalamazoo College in 2014.[1] His career experience includes working as a social studies teacher at Consortium College Preparatory High School.[1]

Camilleri represented District 23 in the Michigan House of Representatives from 2017 to 2023 and took office in the state Senate for District 4 on January 1, 2023.[1] In the 2025-2026 session he was assigned to the Senate Appropriations, Education and Career Readiness, Energy and Environment, Finance and Labor committees, serving as majority vice chair of the Labor Committee.[1] He advanced from the Democratic primary on August 4, 2026.[1]

In a 2026 Ballotpedia survey, Camilleri described himself as a father of two, former teacher, and the son and grandson of union auto workers.[3] He said he is running for re-election to keep bringing resources to Downriver and Western Wayne County, and that he supports lowering health care and prescription drug costs, expanding child care access and establishing paid family and medical leave.[3] He also said he chairs the PreK-12 Appropriations Subcommittee and is focused on a moratorium on AI data centers, capping utility rate hikes and passing a state Michigan Voting Rights Act.[3]
