You may be right about Cotton, but Kristol was also an early fan of Palins ..so just because he likes someone, doesn’t NECESSARILY mean they are estab.
And again, the story here is the NYT poll, period.
My understanding is that recently Tom Cotton spoke in a GOP e meeting with Boehner,Cantor et al and told them they need to forget about amnesty. So I’m not convinced either that he leans RINO.
