Yes, this exposes them to us but just this week AP picked up a loony poster at HuffPo and it made the MSM that Sarah plagiarized Newt. This stuff is getting sick.
Even if there were anything to the Obama birth certificate story, does it really matter? The attacks sound just as lame as the libtards efforts to invalidate Bush's victories. It's a silly overreaction and takes away focus from the issues we should be fighting Obama and the Dems on.
