Is it, though? I'd bet that a majority of American voters wouldn't recognize the name Ross Perot, and he had an order of magnitude more support than the Greens and Libertarians combined. Free trade is also still supported by all mainstream candidates in both parties.

Perot was a sort of singular event to be fair; his movement really orbited his personality. If every election consistently produced a Perot-like figure, I'd bet the major parties would take notice.
