Evidence

I have been following the rumors that have been circulating around the Internet suggesting that Sarah Palin lied about giving birth to Trig, that Trig is instead Bristol's baby. All speculation on this seemed to end when Bristol's parents and the McCain campaign announced that Bristol is herself now pregnant, five months along, making it impossible for her to be Trig's mother. For most, that was evidence enough, but for me, that was campaign related and furthermore relied on the honesty of the one whose honesty was in question, circular reasoning.
I've been keeping my eyes open for any evidence that might help settle this question. The evidence would need to come from an independent source, not from Palin herself and not from the McCain campaign. So what is this evidence? It isn't strong but it certainly seems to be real and independent. It is a letter from a Wasilla resident Anne Kilkenny. Snopes.com confirms Kilkenny's letter.
