I have sliced, diced, and parsed the Real Clear site, and I believe that Newt is way way way overoptimistic.
I really don't think we win the senate. If things don't break right, we might even lose one seat.
In the House, my bet is the GOP gains 20-25. That'll be enough to wrestle the gavel away from the bitch Pelosi, but not the tsunami Ginrich is claiming.
