Voto aprobatorio: Diferenzas entre revisións

▲Approval voting passes the [[monotonicity criterion]], in that voting for a candidate never lowers that candidate's chance of winning. Indeed, there is never a reason for a voter to [[tactical voting|tactically vote]] for a candidate X without voting for all candidates he or she prefers to candidate X. It is also never necessary for a voter to vote for a candidate liked ''less'' than X in order to elect X. Thus, after a voter has decided on his preferences, he only needs to decide on how many candidates he will vote: in the case of ''n'' candidates he votes on his ''k'' most favorite candidates, where ''k'' with 0 < ''k'' < ''n'' has to be decided upon (''k'' = 0 or ''n'' is useless anyway). If the voter thinks that the two candidates with the most votes are those which are on positions ''p'' and ''q'' on his list of decreasing preference, with ''p'' < ''q'', he should choose ''k'' between ''p'' and ''q'', i.e., vote for ''p'' but not for ''q''.
