Well, the others deviated from my original question. Since she would be, effectively, allowing her candidate to campaign on her show without giving equal time to the others, wouldn't her show come under some accounting rule of federal election laws? Isn't it kinda like them not showing the reruns of L & O with Fred in them?
Two issues come into play that you bring up.
Regarding the FCC
and the Fairness Doctrine, there are elements of it that still exist that require the STATION or NETWORK to provide equal access for all sides. This eliminates the ability of a broadcast market to have a one owner media empire that only espouses one view of the world without regard to the people who are in the listening/watching area. This used to be a non issue as no company could own more than a couple of stations in a market. That is no long the case.
Regarding the FEC
it is possible that her show, which may or may not pay for air time on a given station [depending on syndication contract] will have to go to a POLITICAL RATE CARD contract for the remainder of the election season if she uses the show as a rolling advertisement. I would assume that a negotiation would be that she would have her production company only pay Political Rates on shows where Obama discussion or visits would be the primary focus of the show and have shows that focused on diet or Book of the Month be on regular syndicated rates. There would also be regulations of the truthfulness of the rhetoric on a paid political program.
As a syndicated production she is NOT required to provide equal access to anyone. She can book any guest she wishes or blackball anyone she wishes. HOWEVER, the station/network do not have those same freedoms.
That is the crux of the RUSH argument. He can have whoever he wants on his show BUT if it is a POLITICAL ONLY show, it should be under the venue of a POLITICAL RATE CARD, not a syndicated talk show. Also, at that point, there is the "truth in broadcast" issue that has to be addressed with which RUSH does not/would not comply.
