With just 6 days remaining until Election Day, who will win the race for U.S. Senate in Massachusetts is still anyone's guess, and recently-released polls show it.
The most recent poll released by Suffolk University shows challenger Elizabeth Warren leading Sen. Scott Brown by 7 points at 53 percent to 46 percent. The poll of 600 likely voters was taken between Oct. 25 and Oct. 28 and had a margin of error of plus or minus 4 percent.
The poll was in contrast to a poll released earlier in the week by the Boston Globe showing Brown with a 2 point lead over Warren. If undecided voters are factored in, the candidates tie at 47 percent. That poll had a margin of error of plus or minus 4.1 percent.
Going back to September, a Suffolk University poll showed Warren with a smaller lead over Brown, 48 percent to 44 percent with a 4.1 percent margin of error.
It was a total reversal for the Globe whose September poll showed Warren leading Brown by 5 -- 43 percent to 38 percent.
