Post-debate, the only two first-tier candidates who held their position were Donald Trump (in the lead) and Marco Rubio (still tied for fourth). The closest to Trump's post-debate 23 percent was Ted Cruz, moving up from a sixth-place tie to claim second place with 13 percent. Ben Carson also got a boost, moving up from being tied for fourth place to sole possession of third place, with 11 percent. Behind these three were Carly Fiorina and Marco Rubio, both at 8 percent support. The two big losers, however, were Jeb Bush and Scott Walker, who moved from being tied for second place down to being tied for sixth place, with only 7 percent support. That's a pretty big drop for both of them, neither of whom can now claim to be even close to "frontrunner" status. Rand Paul and Mike Huckabee both got 5 percent, and no other candidate got better than 2 percent.

Jeb Bush has dropped to 7% support with Scott Walker in equal 6 th place. Bush appears dead in the water and there is probably no recovery from here unless Trump and five others above him tank.

Goodbye Jeb. Can't say it was nice knowing you.
