Oregon's 1st congressional district

Oregon's 1st congressional district is a congressional district located in the U.S state of Oregon. The district stretches from Portland's western suburbs and exurbs, to parts of the Oregon coast. The district includes the principal cities of Beaverton, Hillsboro, and Tigard, all located in the Portland metropolitan area. Geographically, the district is located in the northwest corner of Oregon. It includes all of Clatsop, Columbia and Tillamook Counties, most of Washington County excluding the extreme southeast, and a portion of southwest Multnomah County in Portland. It generally includes most of Portland west of the Williamette River.

The district has been represented by Democrat Suzanne Bonamici since 2012. Bonamici won a special election to replace David Wu, who resigned in the wake of accusations of sexual misconduct.

The district was a Democratic-leaning swing district for much of the 1990s, with a number of competitive contests after 18-year incumbent Democrat Les AuCoin gave up the seat to run for United States Senate in 1992. However, since the district was pushed further into Portland after the 2000 census, it has been much safer for the Democrats; the Republicans have only managed 40 percent of the vote once since 2003. With a Cook Partisan Voting Index of D+20, it is the second-most Democratic district in the state, behind only the neighboring 3rd district covering most of the rest of Portland. It is the fourth most Democratic district in the Pacific Northwest, only Washington's 7th and 9th districts and Oregon's 3rd are more Democratic.
