I learned that a whole campaign of "hope" and "change" can be built on: resentment, tribalism, claims of entitlement yet victimhood, ignorance of history, convenient revisionism, disparagement and disavowing of American duties and responsibilities in the world at large.
A little more seriously: The Obama campaign is principally about the Party and groups ascendent within it.
The Clinton campaign is about dealing with the big picture mess we're in as a country.
The Obama campaign claims to be competent in the area the Clinton focus is on, but hasn't convinced. The Clinton campaign doesn't claim to be about the long term future of the Party.
Both campaigns are about doing things that are overdue. But one will be better at the combination of both tasks. My bet is on Clinton.
