A few people, including Michael Martin, have been making the claim that in many cases, the low academic achievements of minority students can be blamed to a very large degree on lead poisoning.

Given DC’s past problems with massive lead contamination in the water supply, I would be very surprised if lead poisoning was not also a problem here in the nation’s capital.
Well, I’m sure our resident genius, Ms. Rhee, can sweep the lead out if we give her a big enough broom….right?
Remember her claim? That any claims that poverty, child abuse or neglect, lead poisoning, bad dental care, and so on will cause some students to perform poorly are just “crap”.
