There are some posts about negative votes occuring in an election - and even thought it was a mistake, I kinda like the idea.
I've been kicking around the idea of a un-vote system.
A) Each person gets one vote - they can use it as either a positve vote for a candidate or a negative vote against a candidate. So they could vote and + 1 for candidate A or vote -1 towards candidate B.
B) Each person gets a positive and a negative vote - they could positively vote for A and negatively vote for B, +1 for A and -1 for B (or only use one of those options)
Such a system, though crazy
, might force candidates to not go negative against one another so that the other sides voters would be less likely to cast a negative vote against them. The end result could be candidates who have more broad support.
