I disagree Miskie. The MSM is probably sitting on something that they will spring around October and if they ain't, they will make something up. That is their track record and I bet they will do it again this election. It will probably be something stupid and trivial, but it will be used. After all, obumbles cannot run on his miserable record.
They like Obama, but they like ratings more.
If one of them produces something 'fake but accurate', the rest of the media will take that network out for the ratings. They did that to Dan Rather. No honor among thieves, I suppose.
If one of them has something of value, they won't wait long, because they may end up getting scooped by a competitor.
So, if anyone has anything, its team Obama. But Id say its also unlikely, because as the networks scour data, they will probably stumble upon it, and release it.
What I do expect is the networks to run with any rumor they can find, and once they are proven false, quickly move to the next one to maintain pressure on Romney. Sadly, this technique worked with Sarah Palin, so we can expect rapid fire attacks again.
