Obama mentioned individual and mutual responsibility during his speech. I thought it was a very interesting and unusual framing -- 'mutual' casts it as personal responsibility to other individuals, not a generic collective responsibility to generic and impersonal society.
This looks to me like a seed of a major new theme. I wonder if they plan to develop it further, this seems like a very interesting new twist on the old and common theme. It casts collective responsibility in individual terms.
It steals and improves the GOP base. A very, very deep and clever framing, I think. I hope they make it run.
