For those of you serious about the need for third parties: what would you be willing to change to get them?
In order to make third parties viable on the national level, we would need to change a few things. Apart from the campaign finance issues, a fairly fundamental change would need to happen in our electoral methods. In the US for Congress, we use what is called first past the post voting in single member districts, where politicians cut up the country into congressional districts and whoever gets the most votes in those districts win. This voting method tends to a two party system (this idea is known as Duverger's law http://en.wikipedia.org/wiki/Duverger%27s_law ). In order to make it rational for people to vote for a candidate who cannot make it to close to 50%, we have to put into place some sort of proportional representation (preferably single transferable vote http://en.wikipedia.org/wiki/Single_transferable_vote ) where people would vote in multiple member districts and get to rank who they would like to represent them.
That would be something of a radical change, although it is used in Australia, New Zealand, Ireland, Northern Ireland, Scotland, and some cities in the US.
Would you be willing to change the way we vote so that we could get politicians that better represent us?
[What is proposed here would only need an act of congress to repeal a federal statute mandating single member districts and action on any states' part to change the way they elect their representatives. It is in no way a US Constitutional issue.]
