How would you set up public free advice for Obama's campaign?

So the Koch’s are about to fund a huge buy of ads attacking Obama on the deficit.

I thought of a response ad that would show a series of votes in Congress. It would show a quick quote from Obama saying what the vote would do, then a graphic showing the Republicans killed the legislation. These images would pass by faster and faster, and the end tag line would say something like:

Think the Republicans are in favor of deficit reduction?
Think again!

or They don’t act that way!

I’m think of how this could be done through something like twitter (which I don’t use). The idea is that the best ad ideas get retweeted the most. Or maybe they get Facebook liked or I don’t know anything about Reddit. But the idea is that the best ad ideas rise to the top, and then the Dems make the ad.

How would you do this?
