Gallup's breakdown of Obama's job approval by age was illuminating. First off, note Obama's drop-off among young people. Young people were supposed to be a critical component of the new Democratic majority. Granted their approval is still slightly higher than the other groups, but it has far and away been the most volatile, dropping more than any other. This should not come as a huge surprise. Baby Boomers were partial to McGovern in 1972, but swung around to Reagan in the 80s. Young people's political dispositions are still being formed.
