3% for Huck and 2% for Paul are all time lows (or at least tied for all time lows) for both of them.
Also besides Fiorina, everyone else who attended the Fox kids table debate continues to do worse in the post-debate polls. I think there is a Hunger Games aspect to the kids debate. 1 winner and everyone else is a loser.
Rand Paul's assertion that his polls had been going South even before he attacks Trump. That is correct. It started to go down as the field increase, and then go down some more when the focus was on the Iran Deal. On the Iran Deal, conservatives think Rand Paul was too weak, some libertarians think he isn't his father enough to support him.
But unlike Paul's assertion, his poll number also continue to went down after his attacks on Trump.
Gravis had Paul at 1.5%, Quinnipiac at 2%. On Reuters, he fluctuate but he dip as (record) low as 2.5% at one point. YouGov, Fox, Echelon at 3% (also record low for him for their polls). Rassmussen and Morning Consult at 4% but it is a dip since their previous polling. The only outlier is CNN/ORC who had him at 6% or no change since before the debate.
South Carolina = 3%, New Hampshire = 3%, Iowa's average at 3.4%. All down since mid July. Nevada at 4%.
As for Huckabee, the average that I keep put him above Christie and Kasich still.
