Perhaps. However, you can plant the story so that the source cannot be traced.
Well, no, not really.
There are many of us who had the same questions during the 2008 primaries that we do today. There were all kinds of rumors and questions as to who this man Obama really was.
Another unsourced story would not have done a bit of good then. Remember, he could walk on water, raise sea levels. Nobody even questioned him, and it would have taken hard in-your-face unrefutable evidence.
What was lacking then, and still is, is a sourced and verifiable smoking gun. Breitbart site got closer to that this week.
Hoping that, with his shiny image growing tarnish, the evidence surfaces this summer/early fall.
