The Olympics have figured it out.
When they have five cities to pick from (New York, Paris, Moscow, Madrid and London), do they hold a U.S.-style election where the winner doesn't have to get more than 50% of the votes?
They have a runoff election.
If no city gets a majority of the vote, then they knock off the city that came in last and they vote again.
And in the final showdown of Paris versus London, finally, London earned a majority of the vote.
We should elect presidents (both U.S. and Cook County Board) this way, especially in primary elections.
Hold a runoff! Earn more than 50% of the vote or vote again!
