At Thursday night's Massachusetts Senate debate, Sen. Scott Brown (R) charged that Democratic challenger Elizabeth Warren had represented the insurance giant Travelers in a case against asbestos victims. Brown argued, Warren was nothing more than a money-hungry corporate lawyer. If Brown's criticism of Warren's Native American ancestry was a not-so-subtle challenge appeal to identity politics, this attack went straight to Warren's political core. Brown is not telling the whole story about Warren and Travelers insurance, however.
