Whoa – from Rasmussen:
In the end, Brown pulled off the upset in large part because he won unaffiliated voters by a 73% to 25% margin. The senator-elect also picked up 23% of the vote from Democrats. [Our polling shows that 53% of voters in Massachusetts are Democrats, 21% Republican and 26% not affiliated with either party.]
Coakley also barely carried a usually reliable Democratic constituency. Union workers went for her by just six points, 52% to 46%.
Again, the independents won it, just as they did in New Jersey and in Virginia.
In December, the number of Americans identifying themselves as Democrats fell to the lowest level recorded in more than seven years of monthly tracking by Rasmussen Reports.
