Oregon has been voting by mail for quite a while now. NONE of the issues raised by the opposition has turned out to be true. No issues with fraud, turnout is better (but not great on non-presidential election years) and its easier to sit down with a cup of coffee and cast your vote while at home with information available for double checking. Easier and better at the same time. You are living in the past, use today's tech and make it easier to vote.
i really liked oregon voting.
in arizona, i lived in a few different places. whenever i was in the wonder bread neighborhood of gilbert, i could just walk right up and vote. up in tempe with the college kids and higher minority population, there was always a line to vote. a long one.
similar story here in colorado. my wife and i voted at two separate polling places. i voted at a polling place near where we live, which is 50% hispanic. took me about two hours. she voted at a polling place near where she works, and she waited about 10 minutes to vote. basically all white in that area.
this "phenomenon" is well documented.
oregon voting equalizes all of that. should be a model for the nation.
