Elizabeth Warren is running for the US Senate seat currently held by Sen. Scott Brown. Elizabeth Warren is the Harvard professor who worked to establish a consumer protection agency in the Obama administration.
Brown won a special election in January of last year to fill out Kennedy's unexpired term, following the Democratic senator's death in August of 2009.
Warren began her campaign Wednesday morning by meeting with commuters in Boston. By the end of the first day, she was expected to travel to several Massachusetts cities and towns in the central and western part of the state.
