Massachusetts voters have painted the state blue in the past six presidential elections, and the liberal hue is unlikely to change in the foreseeable future, according to a Boston College political science professor.

BC professor Marc Landy analyzed Democrats’ stronghold on Massachusetts’ political life and liberal voting habits at the Massachusetts Historical Society on Boylston Street last night.

In his lecture, Landy cited a series of statistics explaining why Massachusetts traditionally votes Democratic. Landy explained that Massachusetts fits the Democratic voter demographic, which is typically single, non-church-going and college-educated.

“In no other place in the country do you have the concentration,” Landy said.

Landy said the source of the Republicans’ obscurity in the state was the lack of a conservative, church-going voter base.

“Those who attend church once or more a week tend to be Republicans,” Landy said. “The Republican brand does not sell here.”

Republicans have lost their morale in the state and fewer Republicans are running, Landy said.

“You can’t win if you don’t run,” he said.

Massachusetts has become a safe haven for liberals, attracting many who hold similar Democratic ideologies, according to Landy.

The prominence of higher education institutions in Boston further cements Democratic support in the state, he said.

Landy said other states in the Northeast are beginning to resemble Massachusetts’ voting paterns.

“If current trends continue, we may have to talk less about Massachusetts exceptionalism and more about a regional exceptionalism from Maine to Delaware,” he said.

Sanford Ostroy, Brookline resident and retired Purdue University professor, said he came to Massachusetts from Indiana because of the expansive intellectual environment. He said he attended the lecture because of his interest in the upcoming election.

“Data says this is heavily an Obama state, and I’m happy about that,” he said.

Boston resident Calvin Ary, a self-described “political junkie,” had no doubt that Massachusetts would be a blue state in November.

“Of course Massachusetts is going for Obama, for sure.”

Methuen resident Ralph Belmonte said he came to the event because he was concerned about Massachusetts’ decreasing national role and the political preferences of Massachusetts’ youth.

“Massachusetts is a small state, and we don’t have as big a role as we used to,” he said. “Massachusetts usually votes Democrat, but the younger crowd seems to be skeptical.”
