However, the standard notion of democracy is "1 person, 1 vote".
Under such a system by only being permitted a positive "half vote", the
voter is forced to vote FOR one of the candidates or not vote at all. A
"complete vote" allows the voter the additional choice of voting AGAINST
a candidate.
If Ann, Bob, and Chuck are candidates, a voter who is ambivalent toward
Ann and Bob, but strongly opposes Chuck could cast a negative vote
against Chuck. Under a "half vote" system, the voter would have to cast
a positive vote for either Ann or Bob (or not at all).
