(1) Guest voting: If you hate your district, you could vote in a neighboring district. The more they gerrymander, the less predictable the election results.
(2) Results-based weighting: The winning candidates get more voting power in the legislature, reflecting how many people actually voted for them. If you win a boring and uncontested election where few people vote, then part of your vote in the legislature would be transferred to the winners who also had more real votes.
(3) Negative voting: A voter could use an electronic ballot to make it explicit that the vote is negative, not positive. The candidate with the most positive or fewest negative votes still wins, but if the election has too many negative votes, then that "winner" would be penalized, perhaps with a half term rather than a full term.
What wild and crazy ideas do you have for using computers to make elections better, not worse?
