Because it's a one-party system. Kinda like communist countries, one party , one ideology.

Communists had different parties. Except some were not allowed to win.

so basically it is like the communist system but worse?

You really think- REALLY think- that politicians would ever be able to put people who know what they're doing in control of the economy? In order to balance the budget, they would have to get rid of so much f***ing shit that they US is doing. Tens, if not hundreds, of thousands of government employees would be fired. They would have to massively cut government benefits.

BTW: Fuck you.

lol you just rekt yourself

Yes, communist system but with 50 shades of conservative/fascist/nationalist/traditionalist.

conservative/fascist/nationalist/traditionalist.

Don't forget liberal/anarchist/libertarian/socialist.

do you really think there are shades of socialist or anarchists in the US politics?

Yes, they most certainly are there. They may not be mainstream or receive that much media attention but they still exist.

There's an American Nazi Party of all things, but few people know of them or even hear about them because the media doesn't cover it. Anyone who's not Democrat or Republican is not really spoken of by the media.
