I calculated the numbers and it seems to be a wash for married 400K income. Loss of state tax deduction offset by increased standard deduction and lower tax brackets. If you add in the removal of AMT, the new plan should be lower.
But if you live in a low tax state, then you will do much better.
I think it hurts home owners though, since the mortgage interest deduction might not apply any more if standard deduction is better.
