important one -- just let me get it out on the table -- is basically -- and this is from work that richard cogan did. i didn't know about this. it's a bias that would lead dynamic spending scores and the budget forces allocations on the revenue side on the revenue target and the house and senate rules disallow taxes to go below the revenue floor or appropriations to go above committee's allocations. under the rule that we're talking about the house dynamic scoring rule if we were to move towards scoring discretionary, any positive growth effects would be scored almost entirely as extra revenues just by the rule itself, not as something that would give you room on the spending side. you would only have the ability to cut taxes more, not to increase spending based on what would pop out of the model. >> steve we know that when congress does things what we have found from listening to the jct folks on the tax side is if the new house rule had been implemented ten years ago, the quality of what you would get would be at one level but they've been working diligently all of these years to improve that
