Why I Haven't Been Watching the Presidential Debates

Why haven't I been watching the candidates for president in any of their debates? Nicholas von Hoffman (on the most recent Democratic debate) and Steve Benen (on last night's Republican debate) explain why: I'd probably lose all faith in American "democracy."
Who anointed these media gasbags to be the interlocutors? And since when did people wanting to ask questions have to be properly "vetted"--why isn't being an American citizen enough?
Foolish questions, I know.
