Why A Rural County Went To Biden 74% to 26% And It Is The Second Richest County In Washington?

Normally rural counties are more conservative and poorer. Yet San Juan County is the second richest county in Washington by per capita income and only has population of 18,557. 74% of its population voted for Biden in 2020.

I find it interesting because it is breaking every "rule" out there lol
