In democracies, decisions are typically expressed by means of a single vote to be cast in favor of the political alliance one considers to be the most suitable to govern the country, or a region of it. Voters, however, do not have the opportunity to also express a vote to censure a political alliance they consider to be particularly harmful, if elected. To fill this gap, we propose a double-vote electoral system where voters are allowed to cast not only assertive (positive) votes but also protective (negative) votes, then emphasize its merits as an antidote to divisiveness.
