"Democratic Senate candidate Elizabeth Warren says she raised $6.9 million in the first three months of the year -- more than twice what incumbent GOP Sen. Scott Brown of Massachusetts hauled in for January through March." The Article Continues "Brown last week reported he raised $3.4 million in the first quarter and has about $15 million in the bank.
