This position splintered this controversy into two prongs: one focusing on Bristol Palin, and a second focusing on Sarah Palin. It was always been the goal of the McCain campaign that the focus be on Bristol, in spite of their pious protestations that “children of candidates should be off limits,” because framing this story to be about Bristol as much as possible would keep attention off of where it belonged, on her mother. Not one shred of concrete evidence has ever been released to demonstrate that Sarah Palin is Trig’s biological mother. We have received one incredibly suspect letter from her physician (which among other things did not even get all of the birth years of the four older Palin children correct.) It does not state explicitly where Trig Palin was born (though it helpfully tells us where he could have been born), when he was born (well, actually, it says 2008), or who actually delivered him.
