It's reasonable to expect that both productions could dredge up enough semi-dormant Clinton controversy to negatively impact her. So for the RNC to go absolutely RepubliBonkers over programming which it knows little about seems monumentally ill-advised.
By loudly pouting in the media, the RNC is attempting to exert undue influence over things they do not own. If the networks give in, the RNC will essentially own them. The media outlets should let them keep their debates to themselves.
As for Priebus, he should stop whining like a 12-year-old about what the so-called liberal media does or doesn't do for Hillary Clinton. Let him call Rupert Murdoch and ask Fox Television to make all the movies they want about the Republican candidates.
For a party that claims a strong desire for limited government and personal freedom, Republicans' inject themselves into the lives of others with complete disregard for their well-being or right to personal freedoms.
