Debate 2-6
Here is what Obama's Senate website says about the poor tired planetarium projector:

One of its most popular attractions and teaching tools at the Adler Planetarium is the Sky Theater. The projection equipment in this theater is 40 years old, and is no longer supported with parts or service by the manufacturer. It has begun to fail, leaving the theater dark and groups of school students and other interested museum-goers without this very valuable and exciting learning experience.
