The US political party system, for most of its history, has had a two party system. Most is a key word here. Bringing the question to today's US party system, the Democratic and Republican parties dominate the US. With that said, it should be noted that within each party are various "wings". Meaning in the Democratic Party for example purposes, there is a left wing of the party and a moderate wing and a conservative wing. This is true for the Republican party as well.
The Communist Party, because communism is a scientific economical and political doctrine.Second Opinion:A political party cannot be educated. The people in the party can. Perhaps your question should be:..."Which (insert country here) political party has the most college graduates as members?"
