Warren's entrance into the race has increased her name ID considerably. In March, 59 percent of voters had not heard of her, but now, just 30 percent have not heard of her. A third of voters have a favorable opinion of the former adviser to the Consumer Financial Protection Bureau, while only 16 percent have an unfavorable opinion. That around half of voters have no opinion of Warren gives the Brown camp a limited opportunity to try to define her. With each day the campaign receives widespread attention (see this week's controversy over comments that revisited Brown's nude Cosmopolitan spread, but the poll was conducted before then), Brown's campaign has a tougher time shaping public opinion about their likely opponent. One line of attack -- Warren's employment as a professor at Harvard Law School -- is not likely to help the Brown camp. Twenty-one percent of voters say Warren's job makes them more likely to vote for her for the Senate, while just 13 percent say it makes them less likely to vote for her. The vast majority of voters say it makes no difference. The Western New England College poll was conducted Sept. 29-Oct. 5, surveying 475 registered voters. The margin of error is +/- 4.5 percent.
