Stevie...if a third party candidate did get in it would have to represent a mandate by the people who voted for change. That wouldn't happen in a vaccum but, rather after years of building a base of people who are tired of what we have had for about 20 years.
To your earlier point, I think 4-5 "third" parties would form and then people would flock to the 1-2 that best represent their viewpoint. BTW...most people in the US are fiscally conservative (primarily a Republican viewpoint) and socially liberal (primarily a Democratic viewpoint).
With The Obama we get $16 trillion in debt. With Romney we get idiotic views on abortion, birth control, immigration, religion, etc.
There is room for a true leader who can build consensus in the middle. Gary Johnson is more a figurehead for voters to express their dissatisfaction and build a foundation. Hopefully somebody with outstanding leadership qualities can fill the void for the next election to continue to build toward being viable.
Hopefully everyone here can agree that for, at least, the last 12 years, we have not had a leader in the white house. We will make that streak 16 with either reelection or Romney.
