Even if we don't think it is, the government could let the ad run without taking any action and simply point to your candidacy if questioned as to the reason why.
If we are to really test the law the infraction would have to be blatent. The only way to do that would be with the consent of the media outlet. Who knows, we could find a radio or TV station that will play along just for the free publicity. They aren't subject to penalties if they run the ad, are they?
