To be honest, I think the title of this thread, with these two choices should be "Which party is more decimated?".
State parties like the FL Dems and WA GOP would be in "disarray", by the meaning of the word.
The thing is, Washington GOP controls the State Senate (before it was neutral control, but now I think they have it outright), and their bench isn't completely terrible. They also have a statewide elected official (SoS Kim Wyman) unlike Florida.
Now replace Washington GOP with Oregon GOP, and I think you're right.
