Are Washington State economic politics liberal?

[Seattle]

Yes, historically unions have been quite strong throughout Western Washington. Eastern Washington is a different story, but since the majority of the population lives across the mountains, I'm not really paying attention to them.

The city of Seattle and most of its close (older) suburbs are extremely economically liberal. Once you start going out further, this decreases. Still, overall, the state has a pretty high union rate. I'm not sure what other metrics one can measure economic liberalness.
