THEE Third Party?

Is a three party system better than a two? One would think so, if it is true in the free market than it would seem to hold true in the market place of politics. The truth is, there are plenty of parties that currently exist. But only two that remain dominant and have to this point, been very successfull at keeping all other parties at bay. Imagine a day where a third party gaines the order and support of the masses forcing itself a major player in the political seen. If free enterprise and competition strengthens the deoderant market, it will accomplish much more in the market place of politics.
