If almost every Federal office holder is a liberal and the State votes Democrat in just about every election (this year may be an exception) I would regard that State as Liberal.
Again, you are kind of missing the point but I am beginning to think it is deliberate. Portland has 60 % of the entire state population. It runs the show. You add in Eugene and it is 65 %. The entire Southern Oregon population barely hits 15 %.
One city, overwhelming a state, hardly makes the entire state liberal. Besieged maybe, taxed without representation, certainly. All of which is bad enough without people piling on on saying everyone is getting what they deserve for living in a liberal state.
The sad thing is it is simply hitting places like Oregon first. No state is immune to an over spending government going broke. Even Conservative ones. All those states will be looking to cut services and raise taxes. Is it going to matter that it was a conservative state then? Will that forestall the inevitable? Nope.
