Will Iraqi Elections Fix Anything?

The results in Afghanistan and Iran do not bode well. Lynch worries:

The timing of U.S. troop withdrawals was explicitly designed around the perceived need to keep a larger troop presence through the elections to provide security.  The implicit premise has always been that once those elections are held, the security problems will recede and a more rapid withdrawal could commence. I've always questioned those assumptions -- both that a large U.S. troop presence would play an important or positive role in the Iraqi elections, and that the election would be a decisive moment which would transform the security calculus.
