We also need to consider how many high scorers, who are disproportionately from highly educated immigrant families, would even be US citizens. And I guess based on that question is the 10% cutoff like by year? Because scores fluctuate by year (dipped in the 60s) and the attendance changes by year (more takers in recent decades). So the voting population may be disproportionately younger
But generally, your answer is going to be like affluent suburban Massachusetts or northern Virginia. Socially liberal, but likely with a strong fiscal conservative bent due to the disproportionate wealth of this population. And massively disproportionate Asian political representation, with marginalization of most other non-white ethnicities due to educational inequality. It wouldn’t be a good system. The politics would prioritize the suburbs and neglect everyone else.
