No, there is much fun to do that. After 2000 election, I am done with this BS.
In other words, Political Science is not so easily dismissed after all, as you tried to in post 51.
Nevertheless, in the interests of the thread, I will educate you.
The US uses the 'First Past The Post' ( FPTP ) electoral system...
https://en.wikipedia.org/wiki/First-past-the-post_voting
There are plenty of online literature on the details of it, but to sum it up, FPTP is the oldest and arguably the most transparent electoral process, and that over time, the electoral environment tends to stabilize out to two dominant parties. In the US, the Communist Party of the USA ( CPUSA ) is a legitimate entity, as with the Libertarian or any other party. The burden of preeminence, meaning surpassing others, rests entirely upon the members of the parties. It is up to them to convince the populace to come to their sides. So if the CPUSA managed to convince enough Americans, over time, it could be the CPUSA vs Republican, or the CPUSA vs Democrats. Less likely is a three-parties competition. Not impossible, just not likely.
Your Chinese Communists are
TERRIFIED of even this most basic electoral system. Not because the Commies would be voted out of office, and no one is predicting that, but because of even the
POTENTIALITY of being voted out of office. No wonder the Chinese communists have to resort to personality cults.
So it looks like you are not so knowledgeable about Political Science 101 after all. And I have not even touched multi-party politics as so common in Europe.
