The American political system is viewed as one of the most democratic governments. Given its huge geographic area it is surprising to note that the country can still vote fairly and even elect a black person as the head of state. Due to the strength of the American constitution and amendments thereafter, it is fair to claim that the two party system will be here for a long time or is here to stay. The only way that would make it possible for the two party system to wane off would probably be a combination of the following factors.
Firstly there would need to be a significant change in the legal structure not only of politics but in general. Secondly there would be need to change the mode of thinking and ideology of the American people. Otherwise there would be need for a concerted effort to raise funds, choose candidates and campaign for them to have them elected.
