"Gabriel Gomez is running for Senate in the Commonwealth of Massachusetts. He’s a first generation American, a Naval Academy graduate and former Navy SEAL, and a father of four.  Gabriel will be an independent voice in Washington focused on long-term problem solving — not his next election," Huntsman wrote in an email from his political action committee, Red Rock PAC, on Friday.

Huntsman goes on to reference a barrage of negative attack ads supporters of Rep.

"His opponent is part of the problem: he's been in Congress for 37 years and votes with his party leadership 99 percent of the time," Huntsman continues in the email. "Given he has nothing positive to run on, he and his party have been using money and attack ads in an attempt to drown out Gabriel’s message of common sense reforms."

Recent polling has shown Gomez trailing Markey. A UMass Lowell poll found Gomez trailing Markey by 20 percentage points.

Gomez is hoping to shift the race's momentum in his favor with the help of former Sen. Scott Brown (R-Mass.), who plans to campaign for Gomez on Monday, ahead of the Tuesday election.
