If the debates are run in in the same Democrat-partisan way as they were under Martha Raddatz and Candy Crowly in the 2012 debates, where they co-debated alongside Joe Biden and Barack Obama, and in Crowley's case fronted false information that bailed out Obama (and was not corrected by CNN until a day later when no one was watching), then Trump not participating with that kind of bias against him is a damn good idea.
