[EM] Question about the Plurality Criterion

2013-06-24 Thread Benjamin Grant
As I have had it explained to me, the Plurality Criterion is: If there are two candidates X and Y so that X has more first place votes than Y has any place votes, then Y shouldn't win. Which I think means that if X has, for example, 100 votes, then B would have to appear on less than 100

Hi Ben, 1) they get to vote or rank up to 3 candidates. If someone only wants one candidate to win they need not rank others or if they only had time to learn about two or three and only really liked one or two of those candidates then they could rank one or two of them. 2 and 3 are right.
