The district spans ten counties from the Sierras to Death Valley National Park, including Alpine, El Dorado, Inyo, Mono, Nevada, Placer, Plumas, Sacramento, Sierra, and Yuba Counties.

 CD-03 was created by an independent redistricting commission in 2022 and the majority of voters live in suburbs.   Voters in the district continue to reject the extremism of MAGAs and Donald Trump, making this a classic toss-up district.

Joe Biden received 48% of the vote in 2020 and flipped El Dorado and Sacramento Counties, where a sizable number of voters live, from red to blue.
