Elected officials respond to political pressure, but 100,000 books to officials from across the country do not represent significant political pressure by themselves. They could become political pressure if they turn into a news story, and more people hear about it; but if elected officials are the ones receiving the books, they have a high level of control over how much attention the story receives, and since they don't want to be subjected to pressure, it's against their best interest to publicize it. Of course, you can create your own publicity to some degree, and I do agree that elected officials are the ones who need to fix this, which makes them a good target in many ways.
