Massachusetts senatorial candidate Elizabeth Warren is a woman on the front line — not just in the War against Women, but leading the defense against the Republicans’ attack on the middle class. “I talk to nurses and programmers, salespeople and firefighters, people who bust their tails every day. Not one of them — not one — stashes their money in the Cayman Islands to avoid paying their fair share of taxes,” she said last night at the Democratic National Convention.

Obama gave Warren more voice in portraying the middle-class problem than he gave to any other public intellectual or policymaker besides his White House economic team.  That’s because she has been fighting for the middle class for years.  Warren chaired a congressional panel overseeing the $787 billion financial bailout of 2009, and she drew up plans in the Dodd-Frank Act for the Consumer Financial Protection Bureau, which her right-hand enforcement man now runs.

Warren has long contested the Republicans’ argument that the middle class suffers from excessive consumerism. “Middle-class families are [not] rushing headlong into financial ruin because they are squandering too much money on Red Lobster, Gucci, and trips to the Bahamas,” Warren wrote in 2003 in The Two-Income Trap: Why Middle Class Mothers and Fathers Are Going Broke.  She’s the perfect candidate now to rally the Obama Democrats against the Romney/Ryan run for economic policies that will only increase inequality.
