Let's not talk partisan politics here...or any designated politics, as all sides employ media tactics and polities. The FCC is the arm of "reason" for one to complain to regarding what any station puts on the air. Each licensing period each station has to prove that they are providing what the people want. You can write the station(s) with your complaints and also write the FCC. There are already rules, some not being kept, regarding what and when some material can be aired. Truly if enough complaints come in, a station manager will make changes. It has happened a few times this campaign series already, btw.
Right now there is a bill before Congress, trying to be reenacted regarding "fair" representation. It sounds good, but what it will do is prevent stations from carrying everything, because to do so they will have to (by law) also present the opposing viewpoint. It's not a good thing. Anytime someone begins fiddling with free speech, it's the people who suffer, imo.
But complain we can! Power to the people?
