No 3rd party candidate will never amount to anything. The Republicans and Democrats collude in every state to prevent 3rd parties from succeeding. Ron Paul's first run for the Presidency was on the Libertarian ticket. What he discovered was that every single penny collected from campaign donations had to be spent fighting legal hurdles just to get on the ballot. And he had to fight these battles in every state individually. That left no money to actually campaign with. The system is rigged against 3rd parties and until that changes 3rd parties won't matter.
I guess we’ll just have to start picking off individual house seats with 3rd party candidates and the GOP will be forced to clean up their act or lose.
