My back-of-the-envolope scratches say that if the economy grows anything like the 7.25% it did the last quarter (let's be the conservatives we are and say 5%), then that will bring the deficit down from the current 500 bills or so to about 375 next year.
(A 5% gdp growth of our current 10 trillion economy means an extra 500 billions, the government gets roughly a quarter of that.)
All this assumes no new spending programs - a pipe dream in an election year.
