Yes, it was clear that Cantor didn’t want to address this issue at all. By saying he thinks Obama is a citizen (which isn’t even the issue for eligibility) he avoided the real issue, which is what he wanted.
I think Cantor was also wanting to point out to Gregory that it was Gregory - not Cantor - who wanted to engage in “harsh vitriolic rhetoric”, and who wanted to force his guest to do the same. Sounds like that irony was lost on Gregory, as are (apparently) a lot of things that are obvious to everybody else.
Stuff like that is what makes these leftists so transparent to the thinking public. They’re not interested in respectful, factual political discourse. They are interested in using whatever ploy they can to divert attention from the facts - which is why they have to “Alinsky” Constitutionalists on this issue.
