FORTUNE -- It appears that the next private equity candidate for federal office will again be coming from Massachusetts.
Gabriel Gomez, a principal with Boston-based private equity firm Advent International, this week declared his candidacy for the U.S. Senate seat vacated by John Kerry. Gomez plans to run in the Republican primary (where, so far, he is one of two candidates). If successful, he would compete in the general special election against either Rep. Ed Markey or Rep. Stephen Lynch.
Gomez joined Advent in 2004, after having worked for three years with Summit Partners. He does not have any current board seats, but past ones have included American Radiology Services, Americus Dental Labs, Keystone Automotive Operations, Kirkland's and Synventive Molding Solutions.
Before his private equity career, Gomez spent nine years in the U.S. Navy as both an aircraft carrier pilot and Navy SEAL commander.
Gomez appears to have a bipartisan history when it comes to past political contributions. For example, he contributed $2,500 to Mitt Romney's presidential campaign in 2011, $230 to Barack Obama in 2007 and $250 to George W. Bush in 2004. He also supported liberal U.S. Senate candidate Alan Khazei in 2009 (the race Scott Brown won), and failed Democratic Virginia Congressional candidate Bruce Shuttlesworth in 2011.
Gomez has not yet responded to an interview request.
