Obama wins Presidential debate (Ad) When I said Obama would seek a third term…
They called me a conspiracy theorist, they said it couldn’t happen, that the 22nd Amendment makes it impossible.
But as I explained on live radio years ago, “he could have a proxy… while he remains in control of the administration much like Putin did in Russia.”  Please, watch this now before it’s too late. |
