They may all lead to the DNC, but there may be infighting in the palace. This story is fishy. First it is by AP who have made a career of not investigating Democrats. This story was a plant. Lockhart statement of I do not recall was unnecessary. The Clinotonians want to make sure that Kerry follows a bad August with a bad September. Lockhart only shot to get back on the government payroll is Hillary 2008.
I used to work for the AP. They're not doing the investigating. They just know they have to get it on the wire so they can play on it before the other guys. Strictly business. That doesn't mean they're enjoying it.
