The problem isn't how they play the game called democracy, the problem is democracy, or rather what it has become.
Consider the 5 eyes. Once outstanding examples of democracy, today no one suggests those Nations have the interest of their citizens as top priority. Most democracies today see citizens as something to be managed, lied to during elections and sold out while in office. The change that needs to be made is much more fundamental than the wording of any one law.
Democracy, at least how it is practiced today, has failed the people, the citizens, the Nations using it.
I suspect democracy failed because as a system it loses built in self correction features as it gets larger. Look at individuals and one can clearly see what is in the interest of those individuals and their Nation. Look at 10,000, 100,000 or one million and they become a statistic. For democracy to work representation must be local. Sending your vote hundreds or thousands of kilometers away to be added to millions of others to select a person from a different culture, from a different land, with a different history and different vision of your future to represent you results in the democracy we have today.
Voting as we have been is only changing the players, what is needed is a change of game.
