Effective majority bonuses
Many winner-take-all systems have been described as providing a bonus to certain parties. Systems using single-member districts, particularly first-preference plurality (FPP) usually favor candidates of larger parties. A Common argument for mixed-member majoritarian implementations of parallel voting is an effective bonus for certain parties. Some properties of other mixed systems such as a "winner compensation" element of Hungarian electoral system have been criticized for being effectively just a majority bonus disguised as compensation. Overhang seats in systems using the mixed-member proportional principle are also effectively bonus seats for certain parties.
