ranked voting

Ranked voting systems permit the voter to select multiple candidates, indicating an order of preference.

Although instant runoff is more popular and Condorcet is the most "accurate", I prefer approval voting as a pragmatic solution that is more supportive of third-party candidates. (I, personally, would love to vote Libertarian for representative legislators, without feeling I was "throwing my vote away" and giving up the chance to vote against the worst of the available fascists.)
