That behavior is why 51% of voters consider themselves independent instead of aligned with a political party. It turns out, the majirity of the people are sick of this shit. And the endless wars, empty promises, and all the other disappointments.

That's why Kennedy can win. But the smear campaigns like "he eats dogs" and "he's a conspiracy theorist" are powerful and the meme that "a 3rd party candidate can never win/you're wasting your vote" is even more powerful. That's the only reason Ross Perot lost in 1992. The exit polls showed Perot was the top choice for 40% of voters, but many votes for someone else because they thought he couldn't win. Had they voted for the best candidate, Perot would have been more votes than any other candidate.
