I think people would be disappointed if they did try it. Even if people agree that they don't like the two parties, it doesn't mean that they agree on the same third party. Most likely, their last-ranked choice, but it's going to be named by the most people. The winner will probably be one of those two. I'm all for it, especially if it makes people feel heard. Maybe somebody who made a strong showing can leverage that in future elections. Perhaps there will be a few candidates who can put on strong campaigns without a party support, and that will bolster confidence. But I predict that the most likely outcome is that people say "It's rigged and there's no difference from the old way".
