Gov. Martin O'Malley will visit the first-in-the-nation primary state of New Hampshire yet again next month, this time to deliver a speech to a Democratic fundraiser near Portsmouth.

As the two-term governor weighs a presidential bid, O'Malley has made more trips to New Hampshire than any other potential 2016 contender. The Sept. 26 visit to benefit the Portsmouth City Democrats' annual fundraiser will be his fourth trip in 10 months and second within six weeks. 

While there, O'Malley will also attend an event for New Hampshire state Sen. Martha Fuller Clark, who also has a leadership role in the state's Democratic party.

O'Malley has also dispatched staff from his political action committee O' Say Can You See to New Hampshire, Iowa and South Carolina to help Democrats in the mid-term elections.
