How to Turn the US From a Two Party System into a Multi-Party System
by John Lawrence
Very simply by changing from a first past the post (fptp) system in which the candidate with the highest number of votes wins to approval voting. In the first past the post system a voter can only vote for one of the candidates who are running. In the approval voting system a voter can vote for more than one candidate. In both cases the candidate with the highest number of votes wins. Taking Presidential elections as an example, the fptp system generates the 2 party system. Third party candidates mess up the system because they take votes away from the party they are most closely associated with. Ross Perot took the 1992 election away from George H W Bush since some voters most closely associated with the Republican party voted for Perot while most Democrats voted for Clinton. The second choice of most Perot voters was probably George H W Bush. Perot took 19% of the vote. Clinton won with 43% of the vote, and Bush lost with 37% of the vote. If Perot had not been in the race, Bush probably would have won. If the fptp voting system had been replaced with approval voting, voters could have voted for Bush and Perot. In that case Perot still wouldn't have won, but he wouldn't have taken votes away from Bush. For example if all the voters voting for Perot had Bush as their second favorite and voted for both candidates, Bush would have had 19% more votes thus winning the election. Perot would still have 19% of the vote and Clinton would still have had 43% of the vote, but Bush would have won having garnered 37 + 19 = 56% of the vote!
Making this simple change in the US voting system at all levels would result in a flourishing of third, fourth and fifth parties. These parties would not take votes away from the winners of the election, but would give information about which alternatives were on voters' minds in addition to the platforms presented by the major parties. Eventually, one of the multitude of parties might even replace one of the two major parties. This change of voting systems would let a multitude of parties and ideas flourish instead of cleaving all voter concerns into two parties. It would result in a loss of power for the 2 major parties and do much to decrease the divisiveness in American politics. It would allow real participation by minorities in American politics. The fptp system encourages the division of American voters into two camps in a system where hate and divisiveness can flourish. Approval voting would eliminate the possibility of third party candidates being spoilers in elections and taking votes away from the candidate who would have won if the third party candidate had not been running.
The change from the fptp system to the approval system could be done very simply. Nothing else about the American system would need to be changed, not the ballots, not the counting of votes. The only change on the ballot would be from "vote for one" to "vote for more than one." This change would encourage a multiplicity of candidates and viewpoints and would enrich the American political system. Third parties would be welcomed instead of feared. It would also tend to diminish the role of money in politics as the two party system encourages wealthy donors to give to only one of the two parties. If a viable multi-party system were in place, they would need to spread their money among a multiplicity of parties. Parties with a small number of supporters would be in the position of adding to their membership and growing into major parties based on their ideas and not on their war chests. There are many other improvements that could be made to the American democratic system, but none could be implemented more simply and have such far reaching results. And it doesn't mention in the Constitution which voting system should be used.
