It's very simple:
5 guys are sitting at a table. They get up one at a time, recite their names and towns, and say 'I am not voting for Christopher Shays because...'. One would say 'I am voting for Christopher Shays because...'.
After each one finishes a policeman handcuffs them and takes them away. At the end someone off camera says 'You are under arrest for violating the Shays-Meehan campaign finance reform act.'
We'd then throw in something like 'the following people supported this ad:' and run a list of 100 or so people.
We'd end with a pro-America tag line.
I'd pay for it with my own money.
Nope, the TV station that ran the ad would not be an "accessory." To the contrary, as I've noted in other posts on this thread, as long as a federal candidate is in the equation the station MUST carry the ad and cannot censor it.
I made that comment before getting to your scheme. However it seems to me that the scheme doesn't address the issue, that being that a group can't run such ads in the proscribed time frames. If it's the candidate's ad, with a bunch of other folks names on it, that's not the same thing, and even winning a case based on such an ad might cause a small change in the way the law is enforced, but nothing more.
