You don't know that.(Dan from Michigan)
Actually I think that the ad bans will be stripped based on the recent SCOTUS decision knocking down an Ohio towns ban on door to door solicitation(i.e door to door salesmen, Jehovah's Witnesses's, etc. etc.).
SCOTUS has stated that you cannot ban unwanted soilcitation and add the first amendment conflicts due to the ad ban, you have a slam dunk, IMHO, for the political ad bans to be stripped.
