The preparation of the Benghazi "talking points" seems like typical governmental back-and-forth to me, especially when email is involved. Dozens of people are cc:'ed, some/most respond, each with their personal, professional, departmental and/or - yes, political - interests expressed. It's how government in a democracy (read: "bureaucracy) works: not perfect, but as the saying goes, better than other forms of government.
To try to elevate this messy process into some kind of coverup is absurd. If any group is politicizing this - truly - it's Fox News.
Remember Roger Ailes is a creature of the Nixon White House. He's trying to elevate this into Watergate, clearly, and to pin it on Hillary Clinton, primarily. But it's NOT Watergate. To be a coverup, a CRIME must be covered up. In Watergate there were actual crimes: especially the paying of hush money to shut up the perpetrators of the Watergate burglary - another CRIME approved by Nixon. They especially wanted to shut up E. Howard Hunt, a shady CIA guy with fingers in just about every CIA plot going back to the Bay of Pigs.
That was then. This is now. There is no crime that I can see: disagreements, misjudgments, certainly, as laboriously listed in the Accountability Review Board's Report [pdf] http://is.gd/... which is brutally critical. There is even evidence of the Obama White House's excess of caution & avoidance behavior. But there is no CRIME here unless someone lies under oath, which may happen. That's how they trapped Bill Clinton. My guess is this is Issa's & Ailes' hope - and, the main purpose the investigation.
I just watched the movie "Lincoln" again. President Lincoln 1) prolonged the Civil War and, 2) lied to Congress, in order to get the 13th Amendment passed. Impeachable? Probably, as Lincoln himself muses over in the movie, 'but,' he said, 'in the end the people decide' - by having voted him in for a second term AFTER he had issued the Emancipation Proclamation.
Two things I am sure of: 1) I am glad that Obama, and not Romney, is President. And 2) I am glad that Slavery was Abolished "For All Time."
