Libertarian/Constitution party weakness...did it have to be this way?

[JSojourner]

The two party concept is just so embedded in the American psyche, I don't think we'll see anything different in our lifetime.  Or maybe the next couple of lifetimes.

As a political junkie, I admit...it'd be fun to have about four more colors seriously contending on the maps.  Libertarian and Constitution from the right...Greens and Socialists from the left.
But realistically, I just don't see it.  Especially since the Republicans have some of each (not in name, but in policy) on the hard right of their existing party and the Democrats have some of each on their hard left...think Sanders.  (Who, I know, is technically a Socialist Indie but for all intents and purposes, caucuses with us.)

Anyway -- it's sure fun to speculate about.  I wonder...will my daughter or grandchild ever be represented by a Libertarian Congressman or have a Socialist Governor?  Seems unlikely, but never say never, eh?
