But here's the critical sentence:

In that weird conspiracy-theory freaky thing that people talk about that Trig isn’t my real son. And a lot of people say, “Well you need to produce his birth certificate! You need to prove that he’s your kid!” Which we have done.

My italics. Palin has never produced Trig's birth certificate or a single piece of objective medical evidence that proves he is indeed her biological son. A child with Down Syndrome must have a pile of such records, tests, assessments and ultrasounds that conclusively prove that he is Sarah's biological son. It seems bizarre to me that neither the public nor the campaign (so far as I can glean) has ever been given one of them.

Her doctor, Catherine Baldwin Johnson, offered a two-page summary of Palin's health just hours before polls opened on November 3, a bizarre approach to transparency. The summary omits certain details from Palin's medical history (two miscarriages, one serious), and does not provide any actual documentary evidence of the pregnancy and birth. It was authored by a doctor who has refused to return any phone calls, even from the New York Times, since the moment Palin's candidacy was announced. The hospital has three recorded births on the day Trig was born: the governor's son, by wishes of the parents, was not included on the list. There were only a handful of photographs over eight months that showed Palin pregnant, none showed her as visibly pregnant as with her previous children, and at seven months, her entire staff and all of Alaska's political class disbelieved her:

People just couldn't believe the news. "Really? No!" said Bethel state Rep. Mary Nelson, who is close to giving birth herself ... "It's wonderful. She's very well-disguised," said Senate President Lyda Green, a mother of three who has sometimes sparred with Palin politically. "When I was five months pregnant, there was absolutely no question that I was with child."

On the return flight from Dallas to Alaska, which she says she boarded despite having contractions at eight months - a "strange sensation" she had never felt before, according to "Going Rogue," - the flight attendants on the plane at the time, according to a contemporaneous account in the ADN, had no idea she was even pregnant, let alone in labor of some kind. The questions about this astonishing story are not a function of conspiracy theories and never were. They require no elaborate theory of whose child Trig may actually be. They are simply basic questions anyone would ask of a person who had recounted such an amazing tale. And yet not a single journalist has done so.

This blog has attempted to give Palin the benefit of the doubt on this from the get-go. The Dish was one of the first blogs to post a photograph - of only four - showing Palin somewhat pregnant. At the time, on August 31, 2008, I asked:

Please give us these answers - and provide medical records for Sarah Palin's pregnancy - and put this to rest.

A short time later, I asked simply:

What harm would it do to release the medical records showing that Sarah Palin delivered Trig on April 18 in Wasilla? This is not hard: there must be an obstetrician, medical records, and data that can easily refute this rumor. It is not out of the ordinary either: candidates routinely issue medical records. So let's have them. And then we can move on.

On September 3, Palin was cut off from the press for the following reasons:

In an extraordinary and emotional interview, Steve Schmidt said his campaign feels "under siege" by wave after wave of news inquiries that have questioned whether Palin is really the mother of a 4-month-old baby, whether her amniotic fluid had been tested and whether she would submit to a DNA test to establish the child's parentage.

On September 5, Ben Smith reported that the medical records would be released "very soon". We kept being told that in the campaign and they never were - until the brief doctor's note was issued a few hours before midnight before Election day.
