The so-called 'turnout models' are just short of being prognostications, and are certainly not polls ~ why anyone would pay attention to them as if they can predict is a very good question. With a 9% response rate, and no filter on the input of data from special interest groups, these things have little value.
I'd rather count pigeon droppings on a tiled courtyard.
Most of the “polls” I’ve seen lately are weighted towards “registered voters” v “likely voters”. All part of the special sauce.
