There is a bit of a movement toward Libertarianism in particular, and third parties in general, as people have indeed become more and more
disillusioned with the two progressively more indistinguishable branches of the American political system, but it's not as common as one might deduce
from reading this or any other message board.
Those who post on message boards are, by definition, intelligent and articulate enough to put words in order and convey information. That level of
intelligence and interest is, sadly, still largely the exception rather than the rule. Those who do have the intelligence and interest to communicate
with others by use of the written word generally also have the intelligence and interest to investigate third parties, so support for third parties is
generally over-represented on message boards.
An aside regarding Libertarians gaining access to Presidential debates-- the debates were once organized by the League of Women Voters, who stopped
sponsoring them in 1987, and, when doing so, issued this announcement:
The League of Women Voters is withdrawing sponsorship of the presidential debates ... because the demands of the two campaign organizations
would perpetrate a fraud on the American voter. It has become clear to us that the candidates' organizations aim to add debates to their list of
campaign-trail charades devoid of substance, spontaneity and answers to tough questions. The League has no intention of becoming an accessory to the
hoodwinking of the American public.
In response, the Democrats and Republicans came together to create a nominally non-partisan entity that is actually chaired, bipartisanly, by former
Democratic and Republican party leaders-- the Commission on Presidential Debates. They have systematically excluded ALL candidates other than those
representing the two mainstream parties.
In 2004, a federal court found that the CPD was indeed a partisan organization that represented SOLELY the interests of the two main parties and was
run SOLELY by representatives of those two parties. Also in 2004, Libertarian candidate Michael Badnarik and Green Party candidate David Cobb
attempted to serve the CPD with papers relating to a suit they had filed jointly to attempt to force the CPD to show cause for excluding them from the
debates. They were refused entry to the CPD's offices, so they attempted to serve the papers to them at the site of the St. Louis debates, and were
arrested and taken to jail. This particular story received NO mainstream press coverage then, nor has it since.
Finally, also in 2004, a truly independent organization was formed to challenge the CPD's control of the debates-- the Citizen's Debate Commission.
They were unsuccessful in their attempts to make the debates legitimate in 2004, but have not given up. Their proposal can be found
