If you define every act by government as political then this is political. If by political you mean that politics dictates the outcome that is something different.
It is entirely possible that the State Department could refuse to forward the request to the OIA.
Apparently some here think that "conservatives" look at the case with a guilty eye and then if the next administration is Republican they may be more likely to forward the request.
Maybe the general consensus here that she is innocent and all can see it, except a few friends of PQ and PG, then maybe either the Italians will figure it out or the US will file the request in the circular filing cabinet.
I would suggest to you that the chief *political* consideration for the State Department will be which side of the internecine-war within Italy's judiciary it wishes to support. Here's an issue served up on a platter for the US to be able to meddle!
And especially if it is a Democratic administration in D.C. at the time of any request, the politics of the town will hardly matter given The State of Washington's politics. At best, if Mitt Romney rallies in 2016 and steals the White House, they would simply call in a favour from the State of Washington Democrats before doing the inevitable.
I think back to Gloria Allred's views as given to Piers Morgan, then of CNN. She hinted at the judicial mess Italy has created (using the Knox/Sollecito case as an anology for what was wrong with the place in general), and for her all that was, was trying to do business within Italy. She quickly discerned that it wasn't worth it - because what would be a relatively minor Human Resources issue in the USA, could balloon in Italy into a multi-year, multi-trial civil dispute. She was clear that the legal-climate there needed fixing....
.... which could very well be exploited in this case. No, this case will not result in a massive overhaul of Italy's cumbersome system, with the backroom political-machinations even within a local legal community.... (witness the implied war even within Perugia and the Appeal's level of courts there, where the president of the Perugia Court of Appeal, Wladimiro De Nunzio, is accused of back room dealing to appoint Hellmann so as to undo the embarrassment Mignini caused....
..... which was elevated by Cassazione to a full-blown internecine war.
But imagine someone with even the most dull of political imagination in State Department thinking they'd died and gone to heaven. I mean, someone in the State Department, a political organization, is probably licking their lips, praying to Almighty God, "Please, please, please make them send an extradition request!!!!!"
See what I mean? You make it all sound so clinical - that US Senators always vote on military bases in their States solely on homeland security needs.
Ya right.
