Wow, I really thought this district was gone for national Dems. Either Vancouver is growing very quickly and becoming strongly Democratic to boot, or Biden is starting to win back loggers. And loggers, as we all know, are the coal miners of the forests of the Northwest.
It's not a binary either / or scenario.
Reality is that there aren't tons of "loggers" within the district, but there are plenty up jobs at the Pulp & Paper Mills, as well as some "Saw Mills", within the region.
Fishing Sector likely exceeds loggers within the district...
All that being said, Cowlitz County, WA and Columbia County, OR are effectively "Sister Cities" when it comes to not only the older struggles to bring the Union into the Mills, but additionally bring the Union into the Control of the Docks, as part of the ILWU West Coast Port Strikes.
Union legacy not gone up there, without even going into the Strikes against the "Boss Owned" local Port Authorities, but flips aren't necessarily gonna happen in "Proud Boy Suburban Vancouver", but rather in the Union Halls and Dock and Factory Communities of the Lower Columbia River Gorge.
The most Unionized State in the US (Alaska) appears to be coming around the bend.
