Radiolab - There's an especially great line in here that the US has the perfect democracy for the 18th Century, but younger countries have found ways to improve on the system. We very obviously have a problem with our elections, where we're expecting two enormous tents to contain everyone's political aspirations. Rank Choice voting is the way to let smaller parties, from mainstream fringe parties at a national level like the Libertarians and Greens, to single issue parties at a local level. Imagine a WI party devoted to banning Margarine again. It sounds chaotic, but as the Irish and San Francisco elections show in the episode, what starts as chaotic smooths out over a day of recounts.
We live in a country where a Duopoly insists on the right to our votes, and have made it so that any competition is deemed a spoiler. A moderate revolution would be the only way to break this, but that doesn't seem likely. No one seems happy with the status quo, but reform is going to be near impossible unless we find a way to break up the parties' grip on voting.
