I'm not twisting the numbers.
The national polling was correct, within a point or two. Some state polling was wrong. I think we agree on that.
Since approval polls are ALSO national, I think it is absurd and groundless to say 'based on the 2016 polling, I believe approval polls are worthless and biased.' Since the national presidential polls were right, there is every reason to believe that the national approval polls are ALSO right. I have no idea how you can deny that. Other than sheer, factless partisanship.
If you want to start talking about statisticians and their interpretation of the polls in 2016 - that's a different question and deals with questions of probabliity. And of course probability has little to do with approval polls.
