WA still or used to have residual Asian-American voters that tend to vote republican. Those voters have largely abandoned the Republican party, I suspect further erosion with growing anti-Asian racism fueled by Trump's rhetoric. A similar pattern could be seen in Orange County, CA Vietnamese precincts as Vietnamese-American voters swing further to the Democrats.
Yeah, the GOP really messed up with Asian-American voters. They went from being rather reliably Republican before the 2000s to reliably Democratic in recent times. Trump has just made things even worse.
