Everyone by now has heard, somewhat to our surprise, that Hillary has taken the blame for the Benghazi disaster.  But should we suspect some complicated Clintonian strategy here, some unexpected move in the three dimensional political chess that she and her husband are playing?

Ace has what I think is the answer, and we will know if it's true at the debate tonight.

Ace's take:

"How does this hurt Obama? Well tonight he will be standing next to Mitt Romney. Romney you might recall has made a rather big stink about Obama's failure to lead and his own stellar leadership record.
Here's how he might play this when Benghazi comes up (or he brings it up himself)..."It's all well and good that Secretary Clinton is taking responsibility but my leadership experience has taught me that only the person at the top of the organization is truly responsible. President Obama is at the top of the Executive Branch and he's ducking responsibility. I'd like to know if the President agrees with the Secretary and if he does, why hasn't he asked for her resignation? If he doesn't agree, why doesn't he say who is responsible? Most importantly, why hasn't he taken responsibility from Day 1. Harry Truman didn't say the buck stopped at the Department of State, it stopped at his desk in the Oval Office."
And then it will get ugly for Obama when Romney ads, "And who does the President blame for the failure of his policies to get this economy going? The Secretary of the Treasury? Maybe he blames you the voters for not paying enough in taxes. This country needs a President who accepts the responsibility that comes with the job and doesn't blame his subordinates."
Obama will have no answer to any of that. He also can't fire Hillary because that would cause problems with Team PUMA and his administration would be in disarray 3 weeks before the election
He can't suddenly say, "Oh no, it's me not Hillary who is responsible" because A-he doesn't believe that and B-It's too late. She beat him to the punch, he'll look like he's scrambling to catch up (which he would be).
Mitt's been running a campaign based on his leadership and Obama's unwillingness and inability to lead. The second most popular (maybe the most popular) Democrat in the country, who happens to be Obama's own Secretary of State, just co-signed that charge by stepping into the vacuum Obama's cowardice created.
What Hillary has done is hand Mitt a baseball bat, turned him in the direction of the giant Obama pinata on stage tonight and said, "Have at buddy. Maybe I'll see you in four years".
And what's the downside to Hillary? None. No one is really going to hold her responsible. The DMM (Democratic Machine Media) won't. The GOP certainly won't (update: as predicted) and Obama can't. She'll be hailed as "presidential", "the one official willing to stand up and take responsibility" and ironically enough, a "good soldier". "

At the very least, this is great political theater, played by the experts, on a constantly changing battlefield.  World of Warcraft players, take a lesson from the best.
