The race to replace Rep. Nancy Pelosi (D-CA) is shaping up as an ideological battle over the future of San Francisco — and a test of whether the city’s Democratic electorate is still looking for a distinctly progressive voice in Congress or has begun moving toward a more pragmatic center.California state Sen. Scott Wiener and San Francisco Supervisor Connie Chan, both Democrats, are vying for what is the first truly competitive race in nearly four decades to represent the compact district, covering much of the San Francisco peninsula. The 11th Congressional District territory has long been a central hub of American liberalism, in and around iconic neighborhoods such as Castro, Haight-Ashbury, Chinatown, and the Mission District. And an area in the national spotlight during Pelosi’s two decades-plus in Democratic leadership, including being House speaker from 2007 to 2011 and again from 2019 to 2023.Wiener, 56, has built his campaign around a legislative record on housing, climate change, LGBT rights, and public safety. He is generally viewed as the more moderate, pro-housing Democrat in the contest. Chan, 47, has stronger ties to the city’s progressive establishment. She’s emerged with the backing of Sen. Adam Schiff (D-CA) and Pelosi, who has represented San Francisco since 1987 and made her support unusually visible by campaigning with Chan and appearing at an event wearing a “CONNIE” T-shirt.
