Endless TV time talking about who will be Romney's VP. It's a simple topic, easily understood by journalism school grads. It doesn't mean much, this election is a showdown on Obama and Obamacare, doesn't much matter who Romney picks for VP. Romney won't say anything until the right time, because there is no gain in announcing his pick early. This story doesn't need any research, all you have to do is get one or more talking heads on camera to pontificate.
But the newsies think people will watch stories on the Veepstakes, the stories are easy and cheap to do, and so we get a lot of them.
