For those of us who missed it, could you give us a rundown of what MD4Bush is/was?
Here's my
MD4Bush primer, which hasn't been updated since last November.
In a nutshell, MD4Bush was a Free Republic poster who baited FReeper NCPAC into further discussing rumors about Democrat Baltimore Mayor O'Malley's alleged marital infidelity. MD4Bush then basically outed NCPAC to the Washington Post, giving NCPAC's PRIVATE FReepmails to the paper, which it reprinted in part.
We still don't know who MD4Bush is, but there are suspicions that he may be Ryan O'Doherty, formerly of the Maryland Democrat Party or another Democrat operative. Matthew Mosk from the Washington Post has admitted that he or his underlings logged on to Free Republic as MD4Bush at least once, purportedly to prove that the FReepmails were real.
