Are countries with a two-party system better off than countries that have 3 or more main political parties?

The reason I ask is because I'm from the Dominican Republic and we are experiencing something that could result in a system similar to the Republican and Democratic two-party system of the United States. We have had 3 main parties for a long time. The PRD, PLD and PRSC. The PRD is a center-left social democratic party, the PLD used to be a center-left party that has gravitated towards a center-right platform in the last decade, and the PRSC is a conservative populist party that is losing a lot of support so now many experts say it will be absorbed by the PLD. I think that the PRSC will disintegrate and we'll be left with 2 parties. Countries with 2 main parties...one center-left and the other center-right tend to be the most stable democracies. The U.S. is a good example of that. So do you think that this is a good thing for the Dominican Republic and its development?

The US is a stable democracy because its economy is vital to the global economy. Stability has more to do with economic power than political policy.





And I wish we had 6 to 7 viable parties in the US personally.
Reply:I could understand a 3 party system in a primary election but when it comes down to the general election, it needs to be a choice between two candidates.





Lets say we have the 3 party system.


Obama - progressive party


Clinton - democrat


McCain - Republican





So lets say 60% of America is fed up with the Republicans in office %26amp; wants out of the war.


So Obama gets 35%


Clinton gets 30%


McCain gets 40%





McCain would win in a 3 party system, even if 60% are very much opposed to him.





That is the flaw of three party systems.
