All of the ideas so far look GREAT!
Just a thought... A lot of people these days have Blackberries, iphones, Droids, etc... what about integrating a small QR Code into the ad? Something that people could scan with their smartphones that would take them to a the campaign site, or another page with more in depth information on Dr. Paul. Basically, I'm trying to think of how we can add depth to the ad.
What I mean by that is this: I doubt that many people will pay much attention to an ad that is just full of text. So I think a simpler approach is better, with some nice graphics and the key points (like the concepts already put forth in this thread). But, at the same time, if possible I think it would be good if we could integrate another level into the ad, so that people who want to know more, can go deeper easily.
For example, this ad:
Ron's picture is made up of text. Though I appreciate the subtlety of using the Constitution, what about using that text to give more information about Dr. Paul? In that way we can have a nice looking ad, that people will see and at first look get the points we are trying to make, but it will also give those who want more information the opportunity to "go deeper" by reading the text that makes up the image.
The QR code is just a perhaps simpler idea toward that same end - adding depth to the advertisement so that it provides as much information as possible to those who want it, but isn't overwhelming to those who glance at it. Thoughts?
