Ron Paul and Dennis Kucinich, two of a kind.?

As you can see from some of the answers to your post, they share a common thread of disillusionment in their supporters. Their followers seem to hold others that don't support either one of those "candidates" as contemptible. They certainly aren't helping their causes. But to your point, I would not be surprised to see some sort of platform party with those two involved in some shape or form. Where there are some fundamental difference they are not mainstream and that would attract quite a few voters that are disgusted with their current party and or are not party affiliated.
