What we have learned
Someone made a mistake and then in no uncertain terms says it was completely their mistake, and the rightwing then makes some bat shit crazy claim that the president wanted to sell a boatload of copies of a book that was never finished, thus he secretly lied for many years that he was born in another country because he thought sounding glamorous and exotic would help sell this never published book.
And that, according to TB, is exactly analogous to a factual account of Mitt Romney committing assault and battery on a gay high school kid.
Only in the rightwing universe.
