Anyway, that's what an Indiana TV PSA tells us; back before the Late Civil Unpleasantness, a Hoosier up in one of the far-North counties entered a single write-in vote that tipped the balance in an election (not for his guy, who only got the one vote); and the Representative that won was the single vote that sent the U, S, into the Mexican war, or, as the PSA puts it, in a nice cheery tone, "military action that greatly expanded the borders of the United States," hurrah!
Okay, this is my country and I'm glad that history worked out like it did but jeepers, tellin' me my one vote could pull the trigger on a fresh wave of imperialist war-mongering is not the best possible way to motivate me. Holy crap, if I vote for Rupert for Governor, is the fed.gov gonna find another Middle-Eastern meat-grinder to toss soldiers into on some vague nation-building mission for people who are probably not gonna do anything good with the nation we build 'em? Or maybe invade and annex Canada? (No, no, noooo. Not smart to try that. They actually live up there, most of them year-round. No sane nation takes that on.)
Taking the single most destructive thing nation-states do besides taxation and telling me my vote could cause it, even if I don't vote for the guy who gets in and votes for it, does not motivate me to vote; it motivates me to stay home and clean my guns, worrying they'll decide an internal frontier is the handiest kind.
