Approval voting article is a stub and anyway it is bad that UnfairVote is the first link despite UV being the anti-approval organization.
IRV article has several lies and uses the name "ranked choice Voting"with no obvious clarification. E.g. “Candidates who are opposed by a majority of voters cannot win an RCV election” and “Ranked choice voting allows voters to vote for the candidate they actually want”. And they included top-three IRV in the same article that says the IRV winner must have a majority. (But no, top three voting allows non-majority winners.)
