Switch to Aussie-style voting (rank all candidates rather than vote for just one). This would be a huge hassle, as voting methods are set by the individual states, but I think that this would be the single most effective thing we could do.
Once people understand how it works, and that they can vote their first rank to the candidate that actually want, using their second as the ‘lesser of evils’ vote, we’d see a huge swing in voting patterns and a leap in smaller parties.
It would also allow us to…stop restricting ballot access. What good purpose is served by limiting whom you can choose (other than to maintain the status quo, of course)? To reduce costs, eliminate runoffs, etc. There are states that allow damn near anyone on the ballot; they seem to manage to pick someone everytime. Yeah, sometimes they have 20 candidates listed, but what does that hurt? You’re going to have an election anyway. Since there are never run-offs with this system, there would be no need to restrict candidates to keep costs down.
It could possibly allow us to eliminate the primary system altogether, or at least reduce the primaries back to the purpose of selecting candidates for the two major parties (rather than selecting the ONLY candidates).
Campaign finance reforms are definitely needed, but I’ve never seen a good, workable plan for doing such. I’m not sure such a creature exists; most seem to be about trading one set of problems for another.
I’d have to agree with Satan about the states ‘playing games’ with their election systems. I live in a state where you MUST register a party affiliation, and once that is done you MUST vote that affiliation in the primaries.
Then too, since our electoral votes are sold as a block, usually nearly half of the voters are totally unrepresented in the Electoral College. Major revisions needed there, as well.
Hassle-free voting? Yeah, that would probably help. I’ve been thinking about this since I heard of Oregon’s attempt this year at mail-only voting. I think it could be done fairly easily, and be fairly fraud-proof as well. (I love computers. :D)
That’s all I can think of offhand…
