that’s not the “internals”, that’s the poll results
the internals would show things like the number of GOP, Dims and Independents in the poll
if you can take those numbers, the internals, convert them to % of those in the poll, and compare them to the corresponding % of GOP, Dim or Indpendents among all registered voters, or among more general surveys of all those likely to vote
then you can see if the survey sample is skewed too much, one way or another, by party, contrary to either registered voters or likely voters in general
if, registered voters in missouri were 100, and 55 were dims and 40 were GOP and 5 were independents, and if the survey had the spread 60 GOP, 30 Dims and 10 independents, then the survey results could be said to be skewed to heavily to GOP voters
I am not saying that’s the case in this survey.
I am saying that without the internals, you can’t know.
What you linked us to is not the internals. Maybe the survey outfit did not give them out.
