Yup talking about dog shit , Go to his sight and run the numbers on a few of his hate party states , The only true way you can follow this sight , do as many as you want , when you do you find out exactly my point that the center of stupidity is in direct relationship between whether it is a red or blue state. Some of the stats this clown is trying to show as proof go back to 1964 a different time totally. His point that this legitimate research depends on what you are looking at and in no way give a total cross session number consolidating what each study does. What are the different aspects that are done as different studies. Grade 4, grade 8, grade 12 also mathematics, science, reading and writing , all different studies. You can look great in one and horrible on everything else.
