You're amusing.
Which has nothing to do with the US Const. Best to not comment in things you know so little about.
It does.
If the congressmen votes for each state weren't decided by a majority vote in each precinct, but would be spread out evenly to the parties getting a certain amount of votes in that state.
Eg, lets say Missouri would have 10 congress seats.
Then in the congrss election, lets for arguments sake say the Democrats would get 30 percent and 3 seats. The Republicans would also get 30 percent and 3 seats.
Then some new parties would get percentages as well. The Libertarians perhaps would get 20 percent and 2 seats.
A radical left party, the Socialist party, would only get 4 percent, and that would not be enough to get a seat. Perhaps a new local party, The Southerners that perhaps caucus with the Republicans, would get 15 percent and the two remaining seats.
To repeat, you don't know anything about the system or the US Const. Worry about your own country, and save your advice about ours. I voted third part Libertarian myself. We have not laws nor Const. related articles that force any type of 2 party system here.
Where do you get the idea that I don't know anything about the US Constitution?
I actually took the Democracy class my senior year in the USA. Did you?
Where do I claim that there are any rules that forces a two party system?
I'm not.
What I am saying is that the current political system in USA favors the two old big parties.
If you by any chance followed the election, it's gone so far that not even the two parties will battle for every state in the presidential race, only in states they think are close.
Is that democracy?
Lucky for us, no one cares what you believe.
We've been having a great discussion here.
What's with the attitude,
sport?
Our Const was written by some of the greatest thinkers ever to grace this planet. We hold what they wrote as essential to Liberty, Freedom, and Democracy, and no ignorant twits here or in your country will ever change that.
Exactly what have I've been wrong about?
No offense, but you should keep your opinions about our Const. to yourself, made all the worse by the fact you don't actually know much about it.
No offence taken.
Again, give me an example on how I am wrong about the US constitution.
See above comments... 
Sorry, but I don't see much in your post other than personal attacks and keyboard warrior antics.
It would be awesome if you could prove me wrong however.
Good luck with everything,
sport.
