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 expert 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?

No - there's no counter-balance and there's just a swing from one to the other.





The US political system, to be honest, has two parties that actually (to outsiders) have quite similar policies. The UK has worsened since Labour and the Conservatives have developed similar policies. We do however have the Liberal Democrats and the nationalist parties (Scottish Nationalist, Plaid Cymru, SDLP) who provide some "checks and balances".
