One more approach would be to give the parties some "veto votes" that  
they can use as they wish during the period between elections. If  
some party in on the losing side in some vote by 5% margin it could  
still veto and use 5 of its veto votes to do that (maybe all losing  
parties would use some of their veto votes).
