Just spitballing here: Assign each voter 100 shares for each candidate. To vote, each voter selects a subset of their shares to constitute their vote. Voters can freely trade shares.
Under this system, a voter would more highly value shares for candidates that are either very high or very low in their preference order (the later so as to exclude them from the vote). Thus, trades would look like each party exchanging shares about which they are themselves ambivalent to gain shares that are more valuable to them.
If you remove the proportional chances part, then it becomes a guessing game of which marginal votes actually matter.
Interesting! Hadn’t thought of this approach. Let’s see… Intuitively I think it gets pretty strategically weird because a) who you vote for depends pretty sensitively on other peoples’ votes (e.g. in proportional chances voting you want to vote for everyone who’s above the expected value of everyone else’s votes; in approval voting you want to vote for everyone you approve of unless it bumps them above someone you like more), and b) you want to buy from your enemies much more than from your friends, because your friends will already not be voting for bad candidates. But maybe the latter is fine because if you buy from your friends they’ll end up with more money which they can then spend on other things? I’ll keep thinking.
