Sen. John Thune:

Right.

Well, I think there are different models out there, as you mentioned, Judy. And, of course, we all take — I think both sides take the best of the models, the things that they like.

But we believe, if you look at where we are today and the growth that's predicted by the Congressional Budget Office, by the Joint Committee on Taxation, which are the two official score keepers that we have to deal with here in Congress, they're predicting, for the next decade, that we're going to grow at 1.8 to 1.9 percent.

To cover the cost of the tax cut, all you have to do is realize, depending on whether you use the CBO or the Joint Committee on Taxation, 2.1 to 2.3 percent annual growth. We think it's very achievable.

We have got an economy that in the last two quarters has grown 3.1 percent, 3.3 percent. Historical average is 3 to 3.5. So if we get anywhere close to normalizing growth, we will blow that number away.

So, it really does come down to what your expectations are, what your assumptions are about growth in the economy. And we think very reasonable, modest assumptions about growth get us to where we totally cover the foregone revenue and the tax cut and actually start getting us to where we start paying down some of the deficit.
