Oregon's 3rd congressional district covers most of Multnomah County, including Gresham, Troutdale, and most of Portland east of the Willamette River (parts of Northwest and Southwest Portland lie in the 1st and 5th districts). It also includes the northeastern part of Clackamas County and all of Hood River County. Generally, most of Portland east of the Willamette River is in the 3rd District. The district has been represented by Democrat Earl Blumenauer since a 1996 special election. It is the second-most Democratic district in the Pacific Northwest, with a Cook Partisan Voting Index of D+22; only Washington's 7th congressional district is more Democratic.
