Historically speaking, third parties have had a limited influence on American politics. Currently, the two major American parties--the Democrats and Republicans--have deliberately crafted platforms designed to address most of the concerns of the voting public. However, it is possible for a third party to seize political advantage by successfully arguing that existing parties are not offering a sufficient solution to a pressing problem. In this way, third parties that gain momentum usually do so by aligning themselves with one particular cause, such as debt reduction or Immigration. By leveraging one specific argument, that resonates with an identifiable segment of the voting public, third parties can temporarily present themselves as fresh alternatives to the "stagnant" positions of Democrats and Republicans. Over the long term, however, it becomes very difficult for a third party to remain new in the eyes of the voter and failure to win office consistently makes it difficult to secure the funding needed to sustain a challenge to established parties.

The United States has had two majority parties since around 1829. Although it isn't impossible, no third party has been able to gather enough support to have as much influence and power as Democrats or Republicans. As such, these third parties are known as minor parties.
There never has been a fourth party. At times a third party has risen, but not lasted long. Teddy Roosevelt in 1912 tried a 3rd party run with the Bull Moose party. He was not successful. The two parties we have are very powerful with lots of money. I doubt we will get a third-party or fourth.
They influenced american politics in many ways for example, third parties have often promoted ideas that were unpopular at first. Over time some of these ideas gained popularity and became a law.
