=== Compromising === |

'''Compromising''' (sometimes '''favorite-burying''' or '''useful vote''') is a type of tactical voting in which a voter insincerely ranks an alternative higher in the hope of getting it elected. For example, in the [[first-past-the-post election system|first-past-the-post]] election, a voter may vote for an option they perceive as having a greater chance of winning over an option they prefer (e.g., a left-wing voter voting for a popular moderate candidate over an unpopular leftist candidate). [[W:Duverger's law|Duverger's law]] suggests that, for this reason, first-past-the-post election systems will lead to two party systems in most cases. |

'''Compromising-reversal''' is a compromising strategy that involves insincerely reversing the order of two candidates on the ballot. |

=== Burying === |
|||
'''Burying''' is a type of strategic voting in which a voter insincerely ranks an alternative lower in the hopes of defeating it. For example, in the [[Borda count]], a voter may insincerely rank a perceived strong alternative last in order to help their preferred alternative beat it. A real-world analogy would be voters of one party crossing over to vote in the other party's [[primary election|primary]] against the candidate they think might beat the candidate of their party. |

=== Pushover === |

'''Push-over''' is a type of strategic voting that is only useful in methods that violate monotonicity. It may involve a voter ranking an alternative lower in the hope of getting it elected, or ranking an alternative higher in the hope of defeating it. Also known as a '''paradoxical''' strategy. |
