Recently, a dozen sheriffs in Washington State announced that they would refuse to enforce the newly passed referendum 1639 which raised the legal age of purchasing a firearm of any sort to 21, expanded background check requirements, increased the waiting period and mandated weapon storage when not in active use.
Predictably, political proponents immediately threatened these sheriffs, who were hired to enforce county, not State, laws, with legal action. Of course, when I say passed, what I really mean is that 14 of 39 counties in Washington decided the referendum was a good idea.
Based on actual voting patterns, the victory of this particular bill can be almost entirely explained by the margin of victory in King County (506k), where Seattle is located, which accounted for 87% the margin of victory of the State-wide referendum (580k). This is a common phenomenon in many States that have a large single urban population. Another classic example is New York and the political dominance of the City in State-wide politics.
