That's kind of a bummer for Obama's one-year Inauguration anniversary tomorrow.
No exit polling was done because nobody was paying attention to the race until the last moment. So, everybody is free to speculate about the causes in a fact-free manner.
My guess about the demographics would be that Today's Youth, who turned out for Obama in large numbers in 2008, have moved on to a new fad.
After 2008, you heard about how Obama's big turnout among people under 30 guaranteed the Democrats victory for the rest of eternity. When it comes to electoral strategy, however, never trust anybody under 30 to notice any elections besides Presidential races.
Here are some details from Rasmusen's last pre-election poll:
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%.
Fifty-six percent (56%) of voters in the state say health care was the most important factor in their voting decision. Brown made it clear in the closing days of the campaign that he intended to go to Washington to vote against the health care plan proposed by President Obama and congressional Democrats.
Twenty-five percent (25%) of Massachusetts voters say the economy was most important.
Forty-seven percent (47%) favor the health care legislation before Congress while 51% oppose it. However, the intensity was clearly with those who are opposed. Just 25% of voters in Massachusetts Strongly Favor the plan while 41% Strongly Oppose it.
Fifty percent (50%) say it would be better to pass no health care legislation at all rather than passing the bill before Congress.
Looking back, 30% say the bank bailouts were a good idea. Thirty-four percent (34%) say the same about the auto industry bailouts.
Todayâ€™s voters in Massachusetts are evenly divided in their opinion of the Tea Party Movement.
Fifty-seven percent (57%) of voters in the state offer a favorable opinion of Brown while 47% say the same about Coakley.
Twenty-eight percent (28%) say Brown is Very Conservative politically; 44% say heâ€™s Somewhat Conservative, and 22% view him as a political moderate.
Thirty-five percent (35%) say Coakley is Very Liberal; 36% say sheâ€™s Somewhat Liberal, and 21% view her as a moderate.
Fifty-three percent (53%) approve of the way that Barack Obama has handled his job as President. Thirty-nine percent (39%) approve of the way Deval Patrick has handled his job as governor of Massachusetts.
