Well unless your party engages in a bloody war with the establishment then technically it still isnt RevolutionaryDo you mean " third party" as in "third positionist"?

Revolution doesn't always imply bloody conflict against an established power. Just massive change. And the Libertarian Party is a third-party group, basically meaning not Democrat or Republican. Your term works just as well, though.
EDIT: And I know the definition of revolution implies violence, but it is used to describe massive peaceful changes as well, i.e. the Industrial Revolution.
