10 days from election day, my prediction is:
- GOP wins MT/WV/SD/AR/CO/AK/KY on election day, but Dems hold IA/NC/NH, and Orman wins in Kansas. GA/LA go to runoffs. 48 D, 49 R, 1 Orman
- Orman remains mum, keeping his powder dry since he'd only be the decisive vote if one runoff goes D and the other goes R.
- Despite a valiant effort, Landrieu loses her runoff in December, giving the GOP another pick up.
- With the eyes of the nation shifting to Georgia as the race that will decide whether Republicans assume guaranteed control or Orman becomes king of the Senate, Nunn's crossover support evaporates as the election becomes a referendum on Democratic control of the Senate. Combined with Dem turnout likely dropping, the GOP picks up the seat and with it, control of the Senate.
So basically, I think Democrats losing the Senate is going to be a long, drawn out, and painful process lasting two months.
