Heavy hitters raising cash for Democratic candidate Martin O’Malley.

Prominent members of a Massachusetts Democratic fund-raising network that boosted Barack Obama in 2008 and Deval Patrick two years earlier are hosting high-dollar events for presidential candidate Martin O’Malley on Tuesday.

The bulk of the state’s Democratic establishment, which splintered in 2008 between Obama and then-Senator Hillary Rodham Clinton, has coalesced thus far behind Clinton. . .

But the three events in the Boston area reflect a residual disenchantment with the Democratic front-runner among some of the party’s local power brokers. . .

But the dynamics between the Clintons and supporters of Obama and Patrick have long been complicated, after Obama’s upstart run against Clinton in 2008, which Patrick — along with other top Massachusetts Democrats like Edward M. Kennedy and John F. Kerry — endorsed.

Tuesday’s events come as Sanders, a socialist, has carved out something of a niche as the liberal alternative to Clinton — a lane O’Malley backers had hoped he would fill. . .

The Boylston Street event is cohosted by, among others, Colette Phillips, a Boston public relations executive who was also an early donor to Obama and Patrick, according to federal and state campaign finance records. Private equity executive David Belluck, a heavy Obama fund-raiser who has helped O’Malley build his Massachusetts network in the past, is also among the cohosts.
