I think that the Tmes perfectly identifies the battle taking place on the liberal side of the aisle.
The liberal elitists with their millions support Obama, the working class dems are for Hillary. Generally speaking, you would think this would trend the opposite direction. For years, Senator Clinton has been chasing Hollywood.
Mr Obama wins disproportionately among people who may be considered the winners in the global economy: the well educated, the mobile and the financially secure. Mrs Clinton's voters are the strugglers, the class that feels itself left behind by an increasingly unfair global economic system.
