This is interesting, but there is no smoking gun, yet. It hardly seem possible that there are no contemporaries of Obama/Ayers who cannot provide more insight to the current paper trail. Are there no human sources?
I truly believe there is something out there that will sink Obama in regards to Ayers and someone has it securely stored away until the right time. I would suspect you’ll see a smoking gun in a few weeks, where there isn’t much time left for Osama/Obama to respond. In other words, its the “October Surprise.”
