I took it to mean "third parties politicize CBO reports" rather than "CBO reports are created with ideological slants," because, well, that's the truth of the matter. You can't criticize a CBO forecast for being slightly inaccurate when politicians decide to change the parameters after the fact.

I think you're correct, but it was poorly worded

Sorry about that, GP is correct with regard to my intent.

CBO reports are done within the confines of the request, opening them up to a garbage in, garbage out scenario. The reports are supposed to be non-partisan, but a report request can be crafted in such a way that it's essentially weaponized non-partisanship.
