What interests the media? Let's look at a couple of stories.
Over the course of the last 30 days, the McCain campaign has raised questions - legitimate questions - about former community organizer* Barack Obama's relationship with unrepentant terrorist William "Bill" Ayers.

The release of papers by the University of Chigago from the Annenberg Challenge revealed that Obama's earlier assertion that "this is a guy who lives in my neighborhood. ... He's not somebody who I exchange ideas from on a regular basis" was, at best, incomplete and inaccurate.
On Monday, it was revealed that Republican VP Candidate Sarah Palin's daughter Bristol, 17, is pregnant and preparing to marry the father.

At other times, I may call him a "former back-bencher in the Illinois legislature," which sounds even less impressive. Maybe I'll just let them choose.
