No we really don't which is the consequence of our rather rigid two party system. It's a bit regrettable since it narrows and obscures debate at times but I suspect when the Bull Moose party of Teddy Roosevelt led to the defeat of Taft by splitting the vote and when the CPUSA folded here in the US because of hostility of support for the extremes due to the Cold War that it all but ended serious 3rd parties (although Perot came close in '92 before he went wacko).
Unfortunatly, all that means is our fringes become lobby groups under the table rather than parties dancing on top of it.
