Since February of 2010, the Two Trigs theory has permeated the Trig Truther community. This is the theory put forward by Jesse Griffin of Immoral Minority that says Palin, for unknown reasons, presented more than one child as Trig between April and October of 2008. The main evidence for this theory is that the baby clearly had some ear deformity in April and early May, but showed no deformity at the Republican National Convention, nor subsequently.
As I have argued here and elsewhere, comparisons of pictures strongly suggest only one baby has been presented as Trig. Below, for example, is a graphic I created showing how the baby's ear from April 2008 aligns remarkably with the ear after September 2008, even though it is clear the ear was either medically repaired or possibly "unfurled" on its own.
I personally am convinced beyond a reasonable doubt that only one baby has been shown as Trig. Even if you don't agree that graphics like this one overcome reasonable doubt, surely you must agree that it's now impossible to seriously maintain the opposite: that it is beyond a reasonable doubt that more than one baby has been displayed.
If I'm right, then how must Sarah Palin view the Two Trigs Theory? I imagine she thinks it's a great boon for her and hopes it will continue to be embraced by many in the Trig Truther community .
One reason for this is that she can easily prove that the theory is false whenever she likes. She surely has plenty of pictures showing the development of the ears over time, and if a medical procedure was done, she could produce records for it.
Moreover, Palin can use the widespread belief in the theory as a way to discredit the entire movement that aims to expose the baby hoax. I would not be surprised to learn she has done that in off-the-record conversations with journalists and others.
That is why it is a shame Gryphen (Jesse Griffin's blog name) has doggedly stuck to his theory, despite new ways of looking at evidence that call his theory into serious doubt. Moreover, his refusal to carry or link to evidence that contradicts his theory, such as the above graphic, raises the question whether even he has much faith in the theory anymore.
If Palin is following his blog, and I imagine she is, I'll bet she's rooting for Gryphen to keep flogging that theory, since it could help her keep the hoax buried.
