Democrat Sen. Elizabeth Warren says Republican policies being promoted by its potential presidential candidates would create an "American nightmare" that would crush opportunities for workers while favoring banks and huge corporations.
The Massachusetts senator and favorite of the party's left wing criticized Wisconsin Gov. Scott Walker for proposing a double-digit cut in state aid for higher education, while ridiculing Kentucky Sen. Rand Paul's economic ideas.

Warren's speech Saturday before several thousand party loyalists at a California Democratic convention in Anaheim was greeted with thunderous cheers while scores of delegates waved signs emblazoned with her name.
