Lt. Gov. Tim Murray announced this morning he will not run for governor in 2014.

Despite acknowledging he has increased his fundraising, Murray said in a statement on his website he will not run, citing his "obligations and responsibilities to my young family."

"As I contemplate the commitment required over the next 20 months (and the following four years as Governor) and weigh that against my obligations and responsibilities to my young family, I have decided that I will not be a candidate for Governor in the 2014 election cycle," Murray said in a statement. "Nor will I be a candidate for any other statewide office in 2014."

Murray had been widely expected to seek the office. As recently as November, he told an audience at a Greater Boston Chamber of Commerce speech he would like to hold the job.

“Like many of you in the room, I would like to be governor,” he said to laughter at the time.

Still Murray had been dogged by questions over an early morning car crash in November 2012, and his ties to Chelsea housing authority director Michael McLaughlin.
