Clackamas has trended toward Democratic margins in recent cycles as Portland's suburbs densified, yet its rural eastern reaches—stretching to Mt. Hood—keep it measurably closer than neighboring Multnomah, with a 2024 presidential margin of D+9.8.

The county's recent history is a story of close margins. The Democratic margin reached thirty-nine points in 1936; the Republican margin reached fifty-one points in 1904. Most other elections have been decided by single-digit points.

Clackamas County's demographics — a population of 423,975, a 79% non-Hispanic-white share, a median household income of $103,517 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Champaign County and Jefferson County.
