I am talking about the traditional ones organized by the Commission on Presidential Debates. If, for some reason, they elected not to, but a different organization (e.g. the League of Women Voters) stepped in, I would resolve that as YES if the debates are materially similar in structure and timing. 

While I think it'd be neat if third parties actually made it onto the stage for once, I will resolve this NO if either of the red or blue team's nominee is absent.
