Frank John Addivinola Jr.

Republican Frank John Addivinola Jr. is running again for U.S. representative in the 5th District in 2014 – or sooner.

“Currently, I am campaigning for the 2014 election. However, shall this position … open up early and a special election is announced, I am certainly prepared to enter that race,” he said Friday, referring to the possibility that when John Kerry moves from U.S. senator to secretary of state for President Barack Obama’s second term, Ed Markey will move to U.S. senator from his U.S. Congressman seat.

Markey is expected to face South Boston’s U.S. Rep. Stephen F. Lynch in a Democratic primary and possibly former Republican U.S. Sen. Scott Brown in a general election.

In the last election Addivinola faced a three-way primary in September against Jeffrey M. Semon and Tom Tierney, with Tierney coming in first districtwide with some 4,824 votes, Addivinola second with 3,529 and Semon third with 3,186. Tierney went on to lose against Markey in November.

“I came in second to Tom Tierney in a three-way race,” Addivinola said at the time. “While I am disappointed, I am definitely not discouraged and look forward to announcing my run against Markey in 2014.” on Friday he identified the fight as being about “common sense and balanced representation in Washington, D.C., for the people of the 5th District and this Commonwealth” and said he would “work tirelessly towards our goal of smaller government, lowering debt and deficits and protecting taxpayers’ money from reckless and irresponsible spending behavior that became the new norm.”

Until 2011, Cambridge had been a single Congressional District (apparently dating back some eight decades) represented since 1999 by Somerville’s Mike Capuano. But the 8th Congressional District became a victim of redistricting that splits it between the 5th and 7th districts, with the 5th cutting through the city from the southwest through the center.

That leaves the 7th as the area bordering Somerville to the west, albeit no closer than where Rindge Avenue meets Massachusetts Avenue; and nearly a third of the city to the east, including East Cambridge, Kendall Square, Area IV, Cambridgeport, most of Wellington-Harrington and a bit of Riverside. The area kept Capuano.

In Cambridge, Tierney got 92 votes, which in this case represented 42 percent of the votes cast in the primary; Semon got 73 votes, or 33 percent; and Addivinola got 54 votes, or 24 percent.

Addivinola, 52, of Boston, teaches law and life sciences at local colleges, has a private law practice and manages a real estate investment fund.

Update: Brown said Friday that he would not be running for the Senate: “I was not at all certain that a third Senate campaign in less than four years, and the prospect of returning to a Congress even more partisan than the one I left, was really the best way for me to continue in public service at this time. And I know it’s not the only way for me to advance the ideals and causes that matter most to me.”
