The US Commission for Presidential Debates is a cosy little organisation co-owned by the Republicans and Democrats. So no surprise that third-party candidates don't get a voice. They should of course get a chance to broaden spectrum of arguments the American people hear – so they tried to serve papers to such effect on the Commission. However all over the country they were prevented from serving the legal documents by security guards. In fact the Libertarian and Green presidential candidates were arrested as they tried to serve the papers… a totally unacceptable denial of due process in my view.
