As Democrats prepare to gather in Worcester for the party's nominating convention, Grossman is widely expected by party insiders to win the delegate vote despite trailing Coakley in the polls. Coakley, however, remains the only candidate in the race currently polling ahead of expected Republican nominee Charlie Baker.
Coakley leads Baker 36 percent to 29 percent in a hypothectical matchup, while Grossman trails Baker 27-24, within the 3.5 percent margin of error. Coakley's seven-point lead over Baker is down from 13 points in February, while Grossman has narrowed the gap slightly with Baker that was five points at the time of the last poll.
