The Barrett boys (and their dad) have used Khan Academy to enrich all their learning. I recommend it strongly. Most people reading this post may not need this PPACA/Obamacare primer, but it is very good and bias free.  Check it out and more important, please pass it along to someone who can benefit from a better understanding of the structure of this law that is currently creating such cultural consternations. Enjoy!
