Boston (CNN) - Massachusetts Democratic Senate candidate Martha Coakley sounded confident as she voted Tuesday morning in a special election to fill the final three years of the term of the late Sen. Ted Kennedy.
Speaking to reporters after she cast her ballot at an elementary school in Medford, Massachusetts, near her home, Coakley was optimistic that she would win, saying "we've been working every day."
Coakley, the state's attorney general, is battling Republican state Sen. Scott Brown. A new poll released Monday afternoon indicated that Brown had a 7-point edge over Coakley, with 2 percent backing Joseph Kennedy, a third party candidate who is not related to the late senator. Other recent partisan and non-partisan surveys suggested the race was a dead heat.
Brown votes later Tuesday morning at an elementary school in Wrentham, Massachusetts.
