Template talk:Electoral systems
i think this list should be limited to commonly used systems: those that are (or have been) used at a national level, or in many places for local government elections. otherwise it'll quickly become huge. i would like to have included approval but afaik it still hasn't caught on, and if you include one such system you have to include them all. condorcet is also rare but it was possible to include it under the single "preferential systems" link.
