Cowlitz County, anchored by Longview and its industrial port, once reliably backed Democrats in federal races but has moved more than 30 points toward Republicans since 2000, tracking a broader rural realignment across the Pacific Northwest.

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

Cowlitz County's demographics — a population of 112,360, a 83% non-Hispanic-white share, a median household income of $76,531 — 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 Swift County and Dunn County.
