Poll: In Massachusetts Senate Race Warren and Brown Tied
October 30, 2012(CNN) -- The high-profile Senate battle in Massachusetts remains neck-and-neck in the final eight-day sprint to Election Day, according to a new poll released Monday.
Republican Sen. Scott Brown holds a slender edge over Democratic challenger Elizabeth Warren, 45% to 43%, among likely voters, the Boston Globe survey shows. That margin falls well within the sampling error, meaning the candidates are statistically tied.
When only undecided voters were polled, the survey shows the race gets even tighter with both candidates tied at 47% each.
The new poll comes after a string of polls in the last couple of months showed Warren with a slight advantage over Brown, including the Boston Globe's last survey at the end of September, which indicated Warren was ahead by five points. The incumbent senator, however, had an edge in a couple of polls during the same time period.
Monday's new survey underlines the intensity of the competition between the two candidates, one that has remained close for the last year.
The poll also comes out one day before the two are scheduled to face off in their fourth and final debate, to be hosted at the WGBH studios in Brighton and moderated by CNN Chief National Correspondent John King.
As of Monday afternoon the showdown is still slated to take place Tuesday night, but both campaigns canceled their public campaign appearances on Monday due to concerns about Hurricane Sandy.
The Boston Globe survey suggests Brown may be riding on a modest rise of support in Massachusetts for GOP presidential nominee Mitt Romney. While President Barack Obama still maintains a solid 52%-38% lead over Romney, the 14-point gap is narrower than the 27-point margin found in last month's Boston Globe poll.
For the poll, the University of New Hampshire Survey Center interviewed 583 likely voters by telephone from October 24 through October 28. The sampling error is plus or minus 4.1 percentage points.
