What I wonder is, how do such people (Lerner, Holder, Obama) still have any credibility in the minds of those who vote for them? (well, those who vote for them receive their information through filters, just like you and me, and so they'll probably never know that these hard drives, laptops, data, "disappeared") Which leads to the follow-up question: how can we get this news to reach those who vote for these people, given they (or their filters) would avoid such a story in the first place?
