The Colville Reservation is larger than most counties, and originally much larger. Unfortunately the northern part of the Res had gold, and that was confiscated. The Res is dry, dusty scrub or ponderosa pine forested uplands. One of the three paved roads on the Res washed out in 1987, and hasn't been rebuilt. When the Federal government needs to cut expenses (always) the country's indian reservations are a "no constituency that matters" choice. The only way to get the tribes their due is to make them a voting bloc, and registration was the only way to do that.
From Keller it was a sixty five mile round trip to the court house to register, and bringing the service there seems obvious to me. Washington State law dictates what a registrar must do with all registration forms. Even if you know the registration to be bogus it must be turned in to be sorted by the county office. Even if you have used a form scribbled on to get a ball point pen to write it must be turned in. No exceptions. Partizan registrars, like me, of course focused on people who would vote our way. I never asked anyone if they were a D or R, but I could guess.
I can still taste that red dust from the Res, but we swept the county for the Democrats and of that I am proud.
