One could develop mechanisms, that make the ability to compromise and negotiate outcomes, a requisite to holding offices, even after elections. This could for example happen, by the small minority parties (who are usually filtered out in most democracies) negotiating the voices they represent to another party that will enter representation, in return for representing a certain view-point. This would prevent votes from being lost and would make the ability to compromise and "secure" these votes more important then populist behavior.
