What are the two political party of the US?

Answer- There are many political parties in the United States. Currently the two largest political parties are Democratic and Republican. Political parties constantly change within each nation throughout history, mostly because new political and social issues form as the times change. In the U.S. the third largest party is the Libertarian Party. Libertarian affiliation is growing partly because many are beginning to view the "War on Drugs" as a waste of time and tax dollars. Research may suggest most drugs users arrested do not stop the use of recreational drugs unless medical attention is sought after.The legalisation of gay marriage and civil unions is also commonly supported by libertarians, an issue that is coming up in about every U.S. state. Research facts, and the different values of the political parties in U.S., maybe yours will grow to be largest if you believe you can change things. *Correction - the Libertarian Party is no longer the third-largest. That place is now held by the Constitution Party.
