3 million responses?
Not scientific, indeed.
No, the results are not statistically significant as an indication of the feelings of the entire country.
However, it is socially significant to see that the vast majority of those bothering to vote are statistically evenly split between giving an A and giving an F. Further, those who are willing to enter the middle ground (B, C or D) are statistically insignificant among those bothering to vote. Yes, either you love him or hate him.
What remains to be seen is how many more will join the ranks of those who hate him, and how soon they join that cohort. My money is on the ranks swelling sooner rather than later, and that once joining they will not swing from the far end of the bell curve.
stay safe.
