don't people have to take civics in high school anymore?
Nope. That's why I strive so hard for accurate thinking. Many people are very passionate about beliefs which are inaccurate.
In Illinois last year we had an election for governor. The Democrat incumbent is, IMO, a fool. The Republican candiate was the incumbent state treasurer, and I wasn't happy with her either. So I voted for the Libertatians out of frustration.
The small victory here was that since so many voters were frustrated, many did the same thing. So, since the Libertarians got more than 15% (I think) of the vote they are guaranteed a spot on the next ballot.
These are all the things that had to happen in order for there to be a third party candidate next time.
To be fair, we can have as many politcal parties as we want in the process. Candidates don't have to be Republican, Democrat or even Independent, they can be whatever they want and run for any office.
You can run. The problem is that you only have a realistic chance if you are a Rep or Dem. Are there any third party members of Congress? I can't remember.
