Before you get caught up in some less important debate about the presidential debates, remember:
The presidential election debates haven't been sponsored by a non-partisan group since 1987.
Here's what the League of Women Voters had to say about it on October 3, 1988:
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.Source: wikipedia - US Presidential Election Debates
