Shortly after the next debate, we will be seeing caution signs:
Watch out for derailed bandwagons.
Those who are still struggling at 0%, 1%, 2% maybe even up to 5% will find the donor money dried up.
Several have already hinted at money problems or calling it quits: Perry (money), Christie (no umph), JBush (money, surprisingly).
After that, I'm guessing the next to drop will be Walker, because if the GOPe has to choose, they'll go Rubio over him.
Undetermined how long Fiorina can stay in.
