What just struck me as a bit odd (but maybe rather clever) was that is was advertised on the most political talk station down here ... talk and mostly politics 24 hours a day. It may be good to advertise on talk stations since people who tune in to them are generally there to actually listen.
I'd be surprised if they were that targeted in their approach, but sterotypically a larger percentage of political talk radio listeners are more conservative on social issues (gay marriage, abortion, etc.). At that point the Org would only have to convice them that they should be politically neutral!
