The district includes Marin and Sonoma counties, and its southern border is the northern end of the Golden Gate Bridge. In the first redistricting plan under consideration in California, the district would extend north to the Oregon border, taking all of Democratic Rep. Mike Thompson’s coastal area.
President Barack Obama won the district with 76 percent of the vote in 2008, and it does not seem it would be any more competitive under the proposed map.
Woolsey, who has previously served as the leader of the Congressional Progressive Caucus, was first elected in 1992 to succeed Barbara Boxer (D), who was elected to the Senate.
House Minority Leader Nancy Pelosi thanked Woolsey for her service in a statement Monday.
“When Congresswoman Woolsey retires, the Bay Area will lose a powerful advocate and the nation will lose a tireless progressive leader,” the California Democrat said. “But her powerful legacy of progressive accomplishments will long stand as testimony to her efforts.”
