You are given a list of candidates. You can vote for as many as you want, and each vote is counted as one vote for that candidate - they are not ranked. For example-
Jack votes for Candidate A and C.
Jim votes for Candidate C.
Jenna votes for Candidate B and D.
Jennifer votes for Candidate A and C.
Under this system, C has three (full) votes, A has two, and B and D have one each. So C wins.
What’s this voting system called?
