Reports David Weigel. Republicans wanted their own person in the job, and want the CBO to adopt “dynamic scoring” that takes account of how policy changes affect economic growth. In particular, they think that the CBO overestimates the impact of tax cuts on revenues by not taking account of this effect. I very much doubt, though, that a new CBO director is going to adopt a dynamic-scoring methodology that results in wildly different estimates from the ones the CBO comes up with now.
