The candidate: Veteran Seth Moulton, a Democrat.
The member: Nine-term Rep. John F. Tierney, D-Mass.
The district: Massachusetts’ 6th District, located in the northeast corner of the state, is a reliably Democratic district. But past ethics inquiries into Tierney’s personal finances make him a uniquely vulnerable Democrat. Tierney faces Moulton and Democrat Marisa DeFranco in a Democratic primary. The primary victor will likely face former state Sen. Richard Tisei in the general.
The candidate’s team: Mark Mellman (polling), Dover Strategy Group (mail), Scott Ferson (general consultant), Joe Trippi (senior adviser), Max Glass (campaign manager), Carrie James Rankin (communications director).
