Not so fast guys; King County (Seattle) is a bastion of liberalism, but I assure you that most of the rest of Washington is very, very gun friendly. As a matter of fact, I believe if we could cut King County out of the herd, Washington would be as red as Texas.
The Washington State constitution is not ambiguous a bit about the right to keep and bear arms. Washington has about the most liberal concealed carry law going and as far as open carry; I don't think it would be a problem outside of somewhere like Seattle or Bellview. A few years back the number of people with "Concealed Pistol Permits" in our county was over 27,000 and that is in a county with a total population of about 80,000.
All that said; the Dumbocraps have political control of the state, but that doesn't necessarily mean that they are all going to commit political suicide.
As is the case in every one of the 50 states, we have to fight the gungrabbers, constantly; they will never give up.
