I believe on the tax cut cost, the $1.5 Trillion amount is if we continue at craptastic Obama era GDP base levels and that the $1 Trillion amount reflects an average increase above those base levels to an average of 1.9% GDP over ten years. I believe that more than a few economists say that if GDP averages about 2.5% over ten years that there is no tax cut deficit, but I'd add a tenth or two for an economic entropy factor.
