With due respect, you contradicted yourself. Kids do read per your examples above. They just don't read about geo-political issues. They are about the Karcrapians and any mindless reality show they watch, not to mention inane celebrities. Actually, that probably is NOT reading. I correct myself.
After 2008 Jason Mattera did a book called "Obama Zobies" where he was the first one to show where Zero had a massive and overwhelming edge in reaching 18-30 year olds---YouTube, web, Facebook, Twitter, MySpace. People who track this stuff say it does matter.
