Well this info and story has been 'out there' but never quite broke through; at least for long enough to make impact; and largely because of Media reluctance; and in more cases; Media determination to prevent it. Certainly, Petraeus 'sex scandal' changed the focus; as it was meant to - not only for obscuring the 'truth of the matter'; but also the guilt.
Now; of course; we have the 'clift' imagery dominating the news 24/7; and Benghazi simply struggles; as a story per a Treason really; demanding Justice. Side story: Obama 'won'- for all intents/purposes - and Obama,Inc. and their constituency could not care less, about Benghazi.
As for Repubs; we now know; that 'taxes' are not the only thing, we are giving up to Obama.
A p.s. of sorts; it was Col. Hunt; who was one of the first to share this info; not too long afterwards. He was on Fox News; various news outlets; the story shared in ‘print’ and online etc. NOTHING came of it - save, that is and again - the Media-buster resignation of Petraeus; and all that followed.
