Aren't most campaign ads produced by a corporation?

Right, but I think when we're talking here about corporations, we mean corporations OTHER than the campaign itself.

("Friends of Cong. Rascal," "Dean for America," etc. may well be corporations, but they are NOT subject to the 30/60 rules as they are the corporations of the campaign itself, i.e., they are the official corporate arms of the candidate's campaign.)

I concur, but I still think the point you made in #59 is spot on. The ad will fall into one of the two categories.

If it falls into category #1 it doesn't break the law.
If it falls into category #2 the media outlet rejects it, unless they are "in" on the challenge.
