This might help someone.
Some time ago on my iPad I deleted the Drudge Report and could not find it in the App Store.
As to why the Drudge Report is not there, no one knows for sure. It is most likely that Drudge pulled it himself. That is not a certainty. I check daily to see if anyone has real proof as to what actually happened.
Yesterday I did a restore on my iPad. I was able to get the Drudge Report back by going to the App Store and retrieving it under products "purchased".
