The Breitbart M.O. has always been to drip, wait for reaction, drip, wait for reaction, drip. They let their target set up arguments vs. Fact 1, then they release the documentation to refute the denial with Fact #2, and so forth.
If they released everything at once, it affords their target the opportunity to manufacture an entire story/excuse/denial making it into a ‘he said, she said’ without a way to confirm who is telling the truth.
If you recall the ACORN episodes, they released one tape; the official ACORN response was that it was a rogue employee, not ACORN policy. So they released another tape, and another, leaving ACORN plain out of excuses and establishing that they would lie about anything.
I don’t care about the drip, drip, drip.
I care about the smug anti-birtherism that they’re couching their releases in. They don’t know better than anyone else that Barry was (or was not) born in Hawaii. It’s really odd and IMO unprofessional of them to claim that he was when they release materials where at different times he fairly obviously claimed otherwise.
