This is a good overview, although you do leave out and somewhat dismiss the group that it’s perhaps most important to influence, and that’s the non-noisy, disenfranchised would-be voter, who doesn’t vote because he/she feels there is nothing to be gained by voting b/c all polls indicate that his/her vote will be wasted due to the politics of the state they live in. They could still vote and there might be some slim chance of it going the other way, but the system doesn’t favor that outcome, and they quietly want to hold on to their ideals over compromising those ideals in order to cast a vote that won’t matter. I think there are a large percentage of Americans in this camp (I’ve been in it in the past; not currently), and arguments like what you’ve presented just act as another silencer to their frustrations. Yes, it is hopeless for them not to vote, but why is it that way and how can we change it? Not by compromising ideals on a vote that does nothing. It’s not a protest vote. It’s a “well, shit, what’s the point.”
