The Massachusetts Senate race between incumbent Republican Scott Brown and Democratic challenger Elizabeth Warren remains a close one in a new Suffolk University/7NEWS poll, though it appears that first-time candidate Warren has improved her popularity.

The poll shows Warren running slightly ahead of Brown by 48 percent to 44 percent, which is a statistically insignificant lead within the survey’s 4 percent margin of error. By comparison, in May, the same poll had Brown leading Warren 48 percent to 47 percent.
Perhaps more significant is the improvement in Warren’s favorability. Where 43 percent viewed her positively in May, 52 percent do today, the poll found. Brown’s favorability has remained steady.
Poll director David Peleologos credited Warren’s speech at the Democratic National Convention, as well as her recent ad campaign, for the shift.
"The Democratic National Convention appears to have connected the dots for some voters in Massachusetts,” said Paleologos. He said the voters have linked Obama, Bill Clinton, Warren and congressional candidate Joseph Kennedy, whose district includes Southeastern Massachusetts. "Warren benefited not only from her own speech, but from the oratory of others, both inside and outside of Massachusetts.”
The two candidates are scheduled to have their first of four debates on Thursday.
