Hey, I know...why don't we just do away with voting altogether and we can have each party occupy Congress and the White house for four years. Four years for the Democrats, four years for the Republicans, four years for the Green Party, four years for the Socialist Labor Party, four years for the Communist Party of the U.S.A., four years for the Libertarian Party, four years for the Workers World Party, etc,. etc,. etc....
Then, when we get to the end of the list (if we ever do) we can turn around and do it all over again.
Makes about as much sense as what you're proposing here today...
