State Representative David P. Linksy, an eight-term Democrat from Natick, said Monday night that he is seriously considering a run for Middlesex district attorney and will decide in the coming weeks whether to declare his candidacy for next year’s election.

“Obviously, the most important factors are personal and family considerations, but I’ve always had an interest in moving up to the top job in Middlesex County,” said Linsky, who worked as a prosecutor in the office for 14 years.

Last month, the current DA, Gerard T. Leone Jr., announced that he would not seek a third term. The election to replace him is scheduled for November 2014.

Linsky said that he briefly supervised Leone when they were both Middlesex assistant district attorneys, and the lawmaker touted his experience trying all manner of criminal cases.

“I have personally prosecuted literally thousands of cases, and supervised thousands more,” he said. “Middlesex County has a tradition of having great, professional prosecutors in their district attorney’s office, and I would be honored to continue in that tradition.”

On Beacon Hill, Linsky has focused on law enforcement issues, including gun control. He recently filed a bill that would require gun owners to purchase liability insurance, mandate that large-capacity rifles be stored at gun clubs rather than private homes, and require anyone applying for a firearms license to disclose their mental health providers, among other provisions.

The top prosecutor’s job in Middlesex County, the state’s most populous, has launched the careers of several politicians who went on to higher office, including current Attorney General Martha Coakley, as well as former attorneys general L. Scott Harshbarger and Thomas F. Reilly.

Former prosecutors in the Middlesex office have also included Secretary State John F. Kerry and more recently, US Rep. Joseph P. Kennedy III.

Even Leone, who initially said he intended to leave public service when his current term ends, said earlier this month that he was considering a run for the US Senate before ultimately passing.

Asked if the DA slot’s reputation as a political springboard had any appeal, Linsky said, “this is one step at a time.”

The Globe has reported that other possible candidates include Middlesex Sheriff Peter Koutoujian; Middlesex County Clerk of Courts Michael Sullivan; Assistant Attorney General John Verner; Senator Eileen Donoghue of Lowell.
