Majority Approval Voting (MAV) is a modern, [[evaluative]] version of [[Bucklin voting]]. Voters rate each candidate into one of a predefined set of ratings or grades, such as the letter grades "A", "B", "C", "D", and "F". As with any Bucklin system, first the top-grade ("A") votes for each candidate are counted as approvals. If one or more candidate has a majority, then the highest majority wins. If not, votes at next grade down ("B") are added to each candidate's approval scores. If there are one or more candidates with a majority, the winner is whichever of those had more votes at higher grades (the previous stage). If there were no majorities, then the next grade down ("C") is added and the process repeats; and so on.
 
Note that if this process continues without a majority until the last grade ("F") is added, no new rules are needed. Since by that point all grades will have been counted, all candidate tallies will reach 100%. The process above then naturally elects the candidate with the most approvals at the higher grades (D or above); that is, whichever has the fewest F's. This is thea bestconsistent way to resolve such an election, using onlywhere the informationballots onshow thethat givenno ballotscandidate has majority support at any level. However, in this case and otherin cases of multiple majorities, a runoff, if feasible, would be a better way to ensure a clean majority win.
