Considering that he mentions a blurring of lines in with teeth, a song which is most likely about his struggle with drugs could this be about a relapse.

I would say that it could also work as a semi political song considering that Year Zero is totally political. It could be about how confusing it is today because no politican today will ever tell the truth DEMOCRAT or REPUBLICAN, their both too busy fighting each other leaving the average citizen confused as to who they really believe or why they really care.
