Hillary, about to find out what difference it makes.

This is going to be a significant test for Issa, who spearheaded the Fast and Furious investigation but wound up frustrated and impotent, unable to get the truth out of Eric Holder et al., although he did managed to get the attorney general cited for contempt of Congress. The Southern California congressman had better bring his A game and his best fastball as he goes up against seasoned prevaricators like Hillary Clinton, the former secretary of state whom the late Bill Safire once memorably called — in the pages of the New York Times, no less — a “congenital liar.” In fact, what Safire, writing about Whitewater and other Clinton scandals, said back in 1996 is worth revisiting:

Americans of all political persuasions are coming to the sad realization that our First Lady — a woman of undoubted talents who was a role model for many in her generation — is a congenital liar.

Drip by drip, like Whitewater torture, the case is being made that she is compelled to mislead, and to ensnare her subordinates and friends in a web of deceit…

Therefore, ask not “Why didn’t she just come clean at the beginning?” She had good reasons to lie; she is in the longtime habit of lying; and she has never been called to account for lying herself or in suborning lying in her aides and friends.

The leopard hasn’t changed her spots, and it will be interesting to watch the Bill-Hill dynamic play out once again, this time with her as the object of the prosecutor’s and public’s wrath. Nor has there ever been any love lost between Hillary and Obama; she felt cheated out of the nomination by an upstart nobody with a negligible record of accomplishment in any field, but swallowed her pride and took one for Team Clinton in order to maintain her viability to succeed Obama. If he decides to throw her to the wolves over Benghazi, there will be hell to pay.

And hell is what is coming, one way or the other, because this time — unlike the Clinton impeachment — the big dogs are in play, in the form of hordes of very pissed-off special ops agents, patriotic spooks, forcibly retired generals and clandestine operatives who know where the bodies are buried. If the Obama administration turned its back on Chris Stevens and the three other brave Americans who died that day for crass political purposes — and, worse, if it let them die as collateral damage in its own gunrunning operation to Syria — the men and women who stand watch for this country all through the night are going to come out of the shadows, quickly.
