Combined approval voting

Combined approval voting (CAV) is an electoral system where each voter may express approval, disapproval, or indifference toward each candidate.[1] The winner is the most-approved candidate.

It is a cardinal system, a variation of score and approval voting, and is also known as dis&approval voting,[2][3] balanced approval voting (BAV),[4][5] approval with abstention option (AWAO),[6] true weight voting (TWV1),[7][8] or evaluative voting (EV)[9] (though the latter can also be used for variants with more than 3 values.) It has also been called net approval voting[10][11][12] (though this term has a different definition in the context of approval-based committee selection).[13][14]
