UPDATE, 10:22 AM: I should add that it wasn't just on the economy that this debate was lacking. I agree with this re Benghazi from Jeffrey Goldberg:
What we've got now is a discussion about who needs to be fired, and which candidate is in a better position to score cheap points. Does Mitt Romney actually think that Barack Obama doesn't believe that what happened in Benghazi was an act of terror? A larger question: Does anyone seriously believe that Barack Obama, a president who is at war in more Muslim countries than any president in American history, is soft on al Qaeda? And one other question: Does Barack Obama believe that Republicans somehow aren't allowed to raise serious questions about the Administration's response to the attack? Again, I wish the Republicans would frame these questions not to raise doubts about the commander-in-chief's innermost feelings about terrorism, but to ask what specific actions do we need to take, quickly, to try to prevent follow-on attacks? Whatever happened to that whole notion of politics stopping at the water's edge?
