And now for another Great Idea that's Impossible to Implement and Probably Illegal:

Every time any particular nation has an election for leader or ruling party, the rest of the world should get a vote. They should come up with some way of measuring global sentiment, find out which leader or ruling party the world would prefer, and give the world's favourite a 1% bonus. That way the citizens would get to vote for the leader, but if there's a tie the rest of the world gets to break the tie.
