The former Massachusetts governor will serve as keynote speaker at the state party convention, being held September 25 in Concord. Romney's role was first reported by the New Hampshire Union Leader and confirmed by state party officials.
Romney was the main attraction at an August 5 fundraiser in New Hampshire to benefit the House Republican Victory PAC, which supports GOP candidates in the state. One week later he was listed as the "special guest" at an event in the Granite State for the Republican State Committee. Last week he attended a fundraiser in Boston for the Republican Party of New Hampshire.
Earlier this summer Romney donated $20,000 to the state GOP. According to a state party spokesman, Romney's contributed $30,000 since the beginning of this election cycle.
In a statement, state party chairman John H. Sununu said, "Governor Romney has been a strong supporter of the New Hampshire Republican Party and we are extremely appreciative of all the assistance he has given us through this critical election cycle."
Romney's assistance of course could pay dividends in 2011 and 2012, as the state plays a very important role in presidential primary process, thanks to New Hampshire's traditional role of holding the nation's first primary.
