By definition, third parties are made up of fringers who are unhappy with the two major parties.
What do they want? Single issues, a cult of personality, or, like the Constitution Party, take a position (oppose the war on terror) that is crazy.
Third parties don't work, and never have.
Given the progress of the Democrats, it might not be correct to call it a third party, but rather a replacement second party.
"Third parties don't work, and never have."
