I'd Like This Checked by Real Chemists
The Environmental Law Foundation has claimed that 85% of the children's snacks and drinks tested contain unacceptably-high levels of lead. This sounds alarming but, judging by past hysterias, will probably turn out to be overblown.
The Republican Party has the obvious people to organize a check of this. Exposure to lead is more common in urban areas and might explain why urban areas tend to vote Democratic.
