Contrary to other answers, we don't censor the media here - nor should we. But you can vote with your feet. Many fine organizations offer debate opportunities. The candidates have some sway, because unless they participate, there is no debate. But in the end, it is the media who provides the coverage - and candidates need coverage. The media, however, needs viewers. Watch the coverage of debates you support. Be a vocal viewer. Ignore the others. That's the best you can do.
