You can’t keep a good cause down! the libertarian Our America Initiative has revived it’s activism efforts post 2016 election. A recent post from OAI stated:
Debates are the one element of modern campaigns and elections that should be immune to unfair advantages based upon funding and political party structure. Yet, the private Commission on Presidential Debates, created in 1987 by the Democratic and Republican parties, has created a debate duopoly that makes it virtually impossible for candidates other than the Republican and Democrat nominees to participate.
This exclusion is accomplished by applying criteria for participation — agreed to between the two “major” parties — that include a requirement that a candidate be polling at 15% in arbitrarily-selected national surveys. The Our America Initiative believes this requirement to be not only unfair, but illegal. That’s why Our America is leading a challenge to the Commission on Presidential Debates in Federal Court.
