For the first time in history, a President of the United States has been the overwhelming number one topic of conspiracy theorists. President Obama was the main character in 4 of the voted 10 top conspiracy videos!
I find it curious that Obama, as a democrat is thought to be the Spokesman, or puppet of the NWO, since I had always figure this position to be reserved for a Republican. A very conservative Republican at that! But the conspiracy theorist filmmakers did an excellent job of explaining the who, when and why of it all, so that anybody even remotely interested in these subjects should take, or even make the time to watch all of these (rather long) documentaries in their entirety.
You will have a hard time choosing your favorite, because they are all very well made, very entertaining and very scary!
Just pick one!
