Amid a sizable turnout Tuesday, the Bay State picked Obama over his Republican rival, John McCain.
Obama enjoyed the strong support of Gov. Deval Patrick, the state's first Democratic chief executive in 16 years.
Massachusetts voters turned out for Democrat Barack Obama across gender, education and income divides, with Republican John McCain pulling even or ahead among pockets of wealthier and conservative voters, according to preliminary Associated Press exit polls results.
SMART SUPPORT: The more highly educated the voter, the more likely they were to back Obama, who drew his strongest support among those with college or postgraduate degrees. The split with McCain was narrower among voters with associate degrees or some college experience.
SALARY SPLIT: Obama also drew wider support among lower income voters, picking up a significant margin of those earning less than $50,000, while the margin narrowed with McCain among voters making more than $100,000.
YOUTH VOTE: Obama's pitch to the young appeared to be paying big dividends, with voters between the ages of 18 and 29 flocking to him by wide margins. The margin narrowed significantly among voters between 45 and 64.
IDEOLOGICAL DIVIDE: The one bright spot for McCain was among conservative voters who broke his way in large numbers, but Obama more than made up the difference, picking up a larger swath of liberals and topping McCain among moderate voters.
HEALTH/TERROR WORRIES: Most voters said they were very or somewhat worried about not being able to afford health care. Seven years after the Sept. 11 attacks, a majority also said they were very or somewhat worried there will be another major terror attack on the country.
