Obama released it this morning. Dave Weigel explains its importance and predicts the future:
Does this end "birtherism?" I don't think it will. Surely more forgery gurus will tumble out of the woodwork and quibble with the kerning. This document includes the name of Obama's hospital and attending physician, but it doesn't include a footprint, and even though no Hawaii birth certificates like this included that, it'll be a reed for birthers to hang on to.
Does it end the "questions" about Obama? No. I'd expect the focus to shift now to Obama's college records and writings — as Donald Trump has already been shifting them, by asserting that Obama must have gotten into Columbia via affirmative action to make up for what, he speculates, were bad grades.
