When I first ran against Trent Franks in 2004, the local PBS gave airtime to the incumbent and his Democratic opponent.  I was not invited.  I did not find out about the televised "debate" until early that day.

Had I had a couple of days notice I would have filed a federal lawsuit asking for equal consideration from a publicly funded organization.  I don't have a problem with a private broadcaster doing whatever it wants.  But a publicly funded one, no.  Either let me in as the remedy for equal time participation or block the debate from broadcast.  Post-debate I would ask for either equal time with the same questions on the next show or even better, fining them the amount of federal money they receive.  In Phoenix it is 25%...don't know about Tucson.

Of course, I would not stop anyone who wanted to write to the station (whether public or private) to complain about bipartisan or favoratism behavior and demand the letter be included in the stations FCC file for their review at the next license hearing.
