Referenda are becoming a common tool for public decision-making, and as reliance on direct democracy increases, so does the importance of giving representation to strongly held minority preferences. This paper discusses a very simple scheme that treats everybody symmetrically but gives weight to intense preferences: voters faced with a number of binary proposals are given one regular vote for each proposal plus a single additional bonus vote to cast as desired. Decisions are then taken according to the majority of votes cast. We study the scheme in a number of different models and identify empirically plausible conditions under which ex ante utility increases, relative to simple majority voting.
