Assembly Speaker Karen Bass announced on Wednesday that she will run for the congressional seat being vacated by Rep. Diane Watson, D-Los Angeles. The 56-year-old Los Angeles Democrat has been in the Assembly since 2004 and is the first black woman and first Democratic woman to serve as Assembly speaker. Bass will be a strong favorite in the heavily Democratic 33rd Congressional District, which includes Culver City, Baldwin Hills, Ladera Heights, Windsor Hills, Hancock Park, Hollywood, the Wilshire corridor and Koreatown. Diane Watson announced last week that she will not seek re-election, saying she wants to spend more time with her mother, who recently turned 100 and broke her hip. Watson has held the seat since 2001.
