Thought I’d chime in. He probably did say Q but could be referring in this context to Quinnipiac poll, as it is often referred to a Q poll. Pic related.
To further support this point, he goes on to say “and other research centers” implying his mention of Q was referring to a research center, and Quinnipiac could fit the bill for that. Also possible he used that reference so he could give us a shout out with plausible deniability.
