It's a two party system because everyone in US tries their hardest to keep it a two party system. Every election is the most important one ever, so there are "no options".Instead of this, you can stop acting myopic towards elections and punish your party (vote the other one, 3rd party, or even write-in Bernie Sanders/Ron Paul) and force the political powers to answer accordingly if they want your vote for the next time.

The partisanship in the US traces primarily to the voting system. Replace it with something like range voting or approval voting and you would have twelve parties instead of two, at which point passing anything would require a coalition government and cooperation with other parties would be a mandatory prerequisite for government action.

Unfortunately with your plan, you still end up with a two party system. Just one of the current ones has been swapped out.

I disagree. I think the US system with 2 parties is superior to the systems in many other nations where there are multiple parties. The problem with multiple parties is that it is difficult to form a governing coalition. In the US the problem of coalition building simply does not exits (I wonder how many people in the US are even aware of the concept). Basically, the coalition building is done ahead of the elections, by various interest groups aligning themselves with one of the two parties. Thi

This is more a implementation issue of democracy in some countries. Look at the Danish democracy, we have many parties and both currently and historically we rarely have one party governments. It is not uncommon that three or more parties are forming governments. This helps make sure that there is never one entity that decides or hides things from the public.

The issue in the USA isn't necessarily that politicians organize themselves into different groups/parties, but that there is essentially no choice.The election system in the USA is mostly organized in district/state sort of way, where the winner of the state elections gets all the votes. This makes it very hard for more then two parties to participate in the election.Since there is no choice, there is very little incentive to listen to the electorate (always vote for the lesser evil).

It looks like everyone above you in this comment thread is talking about U.S. politics, which is polarized between two political parties, Democrats and Republicans.As long as the United States continues to use first-past-the-post voting schemes to determine the winners in electoral contests, we will continue to have a two party system (https://en.wikipedia.org/wiki/Duverger%27s_law<

Problem is that US has two party system.

Blame that one on the US two-party system. Multiple parties means you can have okay-ish feelings about 2-3 of them, and support people based on their ideas.

This is the problem with the two party system.
