[[Cardinal_voting_systems#Multi-Member_Methods|Multi-winner cardinal systems]] include many systems. The most popular for achieving high levels of [[Proportional representation]] are [[Reweighted Range Voting]], [[Single distributed vote]], [[Sequentially Spent Score]] and [[Sequential Monroe voting]].

Score can be thought of as a [[Condorcet method]] where a voter may only put up to 1 vote (i.e. the maximum number of points allowed) in between any pair of candidates in a [[beatpath]]. That is, a strategic voter whose preference is A>B>C can maximally contribute to A getting more points than B or to B getting more points than C, but not both. A rated ballot A:5 B:4 C:0 with max score of 5 is treated as "A is 1 point better than B, B is 4 points better than C, and A is 5 points better than C", whereas in Condorcet all three [[Pairwise counting|pairwise comparisons]] are treated as "more-preferred candidate is 1 vote i.e. 5 points better than less-preferred candidates." Both Score and Condorcet elect the candidate who can get more points/votes than any other opponent in one-on-one comparisons, though in Condorcet such a candidate may [[Condorcet paradox|not always]] exist.
