I don't know how the U.S. papers are going to report this tomorrow morning, but what is clear is that as far as the Iraqi government (...after the late-night meeting here that brought together all the branches of the state) is concerned, the law must take its course. And as far as VP Biden is concerned, all he wanted to do in Baghdad was to express support for the Iraqi government during what the Iraqis are saying was a routine trip that was scheduled three weeks ago (i.e. before the crises).
So, all the needless nail-biting has come to this: the Appeals Committee will decide who get to run and who doesn't from the list of 511 'de-Baathified' candidates. Which is exactly what the legal mechanism was meant to do in the first place.
I think the U.S. government did the right thing here by dialing down their involvement from Biden's initial outbursts to a position that, to me, seems reasonable: to allow the Iraqis to sort this out through the legal mechanisms in place.
My hunch is that the INA scored a big win with this gambit at Maliki's expense, and I'd be very surprised if Saleh al-Mutlag is indeed barred from running.
