I went through the Qpac poll methodology.
I don’t see major problems with it. They call both landlines and cellphones. They take over 1000 samples. They do not impose a partisan mix. They do measure what their samples produced, but it is not presented.
They do weight results according to Census data for age, gender, region, etc. There IS a mild potential problem with this in that the Census was corrupted to minimize seat loss in Congress.

Thanks, Owen, for sharing your analysis.
Still not good to see Trump losing so much ground to Brandon in recent weeks in this survey when all the others had him gaining steam.
