My dad is a blue dog Democrat who consumes a ton of leftist MSM (WaPo, MSNBC, ABC nightly news, Newskweek, etc. etc. etc.) and I mentioned the Ray Epps thing to him a couple weeks ago, and was actually a little surprised he has never even heard of him. That story is a complete blackout by the the leftist MSM. They don't even mention it to refute it, it just doesn't exist.
Even mainstream "right wing" outlets like NY Post and DailyMail have been doing stories on this peculiarity for a long time. And like the Revolver piece mentions, Epps is just the tip of the iceberg. There are quite a few guys who seemed to be involved in the "breech" who should be easily identifiable and the FBI seemingly has no interest in.
