Trader consensus prices Michael Minogue and Brian Shortsleeve nearly even at 45.5% and 45.0% in the Massachusetts Republican gubernatorial primary, reflecting a tight three-way contest with Mike Kennealy at 10.5% ahead of the critical April 25 MassGOP convention in Worcester, where candidates must secure 15% delegate support for September 1 primary ballot access. Minogue gained ground from his campaign's early March internal poll showing a 29%-16% edge over Shortsleeve among modeled GOP primary voters and delegates, but a March 26 Boston Globe report on Abiomed recalls, off-label promotion issues, and a DOJ kickback settlement during his CEO tenure has fueled scrutiny from rivals. Shortsleeve sustains momentum through attacks on state spending and property tax hikes, while Kennealy lags in recent surveys; convention endorsements, debates, or fresh polls could create separation in this undecided field.
