Someone at the Globe has the reigns pulled very tight and they will spin this forever. Sooner or later though, someone will expose it all for the right amount of $$ (probably coming from the Hillary 2008 crowd).
They can try to spin it, but the SBVFT can put in a FOIA request for the material and do their own analysis. The big question for me is whether Kerry's SF-180 contains any limitations on the kinds of material released. The SBVFT should be able to get a copy of the signed SF-180.
