With this poll, Kasich has pulled within the TOP-10 in the RCP average (he's tied for 10th with Perry, but Kasich's numbers are going up - while Perry's are going down).
Fox will probably not count this poll, as it is not live phone.
It's more about if what this poll shows is reflected elsewhere.
My hunch is that Perry and Kasich make the debate, while Christie does not. Perry's been getting good publicity and Kasich is improving his name recognition, while likely to benefit from an announcement bump. Things have been relatively quiet for Christie, who seems to be on the bubble with notably worse results than Carson, Huckabee, Cruz and Paul.
