Was It "I" or "They"?

So the Green party is no longer threatening to sue Leftdog blogger for reporting on a YouTube video of Elizabeth May's unfortunate speech. The Green Party communications director John Bennett apologized to Leftdog for his hasty email and then stated the following:

In the TVO clip, Elizabeth May clearly says "they" think Canadians are stupid, referring to the opinions of some politicians. She then turns to the questioner and agrees with HIS assessment that a carbon tax is essential. No spin can change that.

Well, let's listen to it again, shall we?

Sure, the "ey" does sound quite ambiguous. But the biggest problem is with the other sentence. It's neither "this assessment" nor "his assessment". The sentence goes "and I fundamentally agree with that assessment". So, even if "ey" is really a fragment of the word "they" - what difference does it make? "They" think Canadians are stupid, but Elizabeth May fundamentally agrees with that assessment, so she's no better than "them".

Mr. Bennett suggests that the second sentence was unrelated to the first; that Ms. May turned to the questioner and talked about "his" assessment. Well, maybe it would have made sense for her to finish the sentence before changing the subject.
