This un-named staffer didn't have the balls to be identified and go on the record.
Either did Deep Throat, but he was telling the truth. She may or may not know Africa is a continent, the larger point is maybe she is unaware of what happened outside of the state of Alaska and was ill prepared to be a VP. Doesn't matter, they lost and it is no longer of any importance. The press has always used unnamed sources, but they usually have to verify through other sources for it to be considered accurate. The change is the papers now will quote an unnamed source, credit the unnamed source, but not have corroborating evidence to back it up and still state it as fact. The way we were taught to report was use those sources, but get at least another solid source, either named or unnamed, to confirm the facts, then find another softer source or evidence strongly supporting the statement and then you could go with it. That was only 20 years ago at a pretty lousy newspaper, the Houston Post.
