SD, I see your point - why not just start your own party? I get it. There are other parties, but that's not the point. The point is Republicans & democrats are automatic bids. They're automatically in the debates. They're automatically on the ballot in all the states. They're automatically within a 50% slot of being the next president. GJ will never win, because a 3rd party is essentially still splitting the votes - and if either a d or an r will be the big winner - it's still a 50/50 chance for the r's & d's regardless of a green party candidate, libertarian candidate, communist candidate, marxist etc.
That's not a how the system is constructed; there are not rules that make this possible - it's a reflection of the monopoly that has been created within the political structure. Republicans & Democrats have a monopoly on the power. That's the issue.
Why does a political candidate even seek affiliation with a political party? You and I know they do so that dumb asses with blinders on will vote for them no matter what they really stand for. So why not abolish all political parties? There would be no more: "I'm a libertarian, so I'm going to vote for Gary Johnson!" or "I'm a Republican, so I'm going to vote for Mitt Romney!" or "I'm a democrat I'm going to vote for Barrack Obama!" Wouldn't it be amazing if people actually knew what they were voting for and not accepting the lesser of two evils? Why can't a debate be between Gary Johnson/Ron Paul/Mitt Romney/Barrack Obama/Michelle Bachman/Huntsman/Santorum/etc instead of a debate between the Republican vs. the Democrat?
What if all of the religions were consolidated to two categories: Jews & Christians. Can you imagine the "butt-hurt" athiest would feel? Mormons? Muslims? Hindu?
