Scott Brown and Elizabeth Warren are tied at 48 percent support, according to Rasmussen. The U.S. Senate race, which pits the Republican incumbent Brown against Warren, a Democrat and Harvard law professor, remains a contentious toss-up. Rasmussen also reports that 3 percent of likely voters in Massachusetts are undecided in the race. This is Rasmussen's first poll of the race since the candidates' first debate on September 20.
According to the RealClearPolitics poll average, Warren has a 1.6-point lead over Brown. The next debate between Brown and Warren will be on October 1, moderated by NBC's David Gregory.
