I don't think that there will be a major national third party. There will be candidates from various parties winning in certain regions such as:
Libertarian Party in states like Colorado, Georgia, Alaska or Arizona
Green Party in areas like northwest California, Alaska, Oregon, Vermont, Massachusetts, Maine, Minnesota, most college towns (The Green Party had a majority on the Arcata CA city council and on the Minneapolis city council) Ralph Nader also won 13% in Humboldt County and 15% in Mendocino and won a few precincts in the two.
Constitution Party in central Pennsylvania, Idaho, Wyoming and Utah
You know, I seriously think the 3 major third parties should do this. It's the only way to bend Duverger's Law and if this is what it takes to see the Libertarians, Greens and Constitutionalists to win more state legislature seats (and also Governorships and Congressional seats).
