I honestly wouldn't want to get the federal government in on this. The only reason states are so liberal on it in comparison to the feds is that the states often just ignore the third parties and don't give them much recongnition anyway. If the feds were deliberately trying to craft a law you'd probably get much higher requirements for a third party to be declared, and the Democrats and Repbulicans would never have to worry about it again. I mean, I've looked at several of the proposals from Democrats and Republicans regarding federal campaign spending laws. Provisions that say, for instance, that you can't run unless you get 20% of the signatures in your district (unless you're a Demopublican). I mean, even IF you were a major party that would be impossible. That's about a hundreds thousand signatures every two years.
