BOSTON — She may be an undeclared candidate, but potential Democratic U.S. Senate contender Elizabeth Warren appears to be gaining support among Massachusetts voters. A WBUR Poll (PDF) released Tuesday puts the Harvard law professor the closest of four Democrats to incumbent Republican Sen. Scott Brown.
When paired in a hypothetical contest, 44 percent of 500 likely voters said they’d vote for Brown, compared to 35 percent who said they would vote for Elizabeth Warren. In similar hypothetical match-ups, Brown topped City Year co-founder Alan Khazei (45 percent to 30 percent), activist Bob Massie (45 percent to 29 percent) and Newton Mayor Setti Warren (no relation to Elizabeth) (46 percent to 28 percent).
