Yeah, you can do all the math if so inclined. The other thing you can do is see how the phone polls match the actual primary voting results (they don't)
In apropo of a thread with iirc @proptermalone.bsky.social about the crosstabs in low-response-rate phone polls, here's a semi-quantitative analysis of why I'm a little dubious about poll results with a >1% response rate.
It comes down to Bayes' theorem
P(A|B) = P(B|A) P(A) / P(B)
