The Atlantic: "No, Liberals Don't Control the Democratic Party"

In a classroom in Harlem, the liberal new mayor of New York, Bill de Blasio, appeared with union leaders in support of his plan to raise taxes on incomes higher than $500,000 to fund public pre-kindergarten. "We're asking this of the wealthy," de Blasio said, "because there are too many working parents in this city today" who need help. 

At the same time, New York Governor Andrew Cuomo was presenting his budget in Albany under a sign that trumpeted: "CUTTING TAXES."

You could hardly get a better illustration of the current tribal divide in the Democratic Party.
