on the effect of tax cuts

Cheap Denny Rehberg is reported to have said that the federal income has gone up a bunch over last year because of the federal tax cuts. Well, I want to know how different the federal income would have been without the tax cuts. Would our budget have been balanced? And Denny, you, of all people, should know that it wasn't the tax cuts that have moved the economy, but the deficits. Or didn't you study economics?
