I see no methodology. There’s no mention of sample size, methodology of selection of voter, etc. There’s no mention of geographical area(s) where this polling was conducted, during what time, nor what the stats look like for absentee or early voting, nor is there any demographic information on what the general control population makeup is or their voting patterns.
In other words, waving this sort of stuff around in front of a retired EE like me, who has studied a lot of probability and stats, leaves me completely non-plussed. You might as well have told me the average price of potato(e)s in three different states - it would be about as relevant to the election as these exit polls.
