Journalist Spencer Rumsey filed petitions Wednesday to run against 14-year State Assembly veteran Andrew Raia.

Rumsey, a Northport resident, is a former Newsday editor and more recently a senior editor for the Long Island Press.

While he is a Democrat, Rumsey circulated his own petitions to run and was not included in the petitions circulated by the Suffolk Democratic Committee. He collected about 700 signatures, 200 over the minimum signature requirement, party officials said.

Raia, 48, a Republican from East Northport, is deputy minority whip and ranking minority member of the Health Committee. He ran without opposition two years ago.

Neither Rumsey nor Raia could be reached for comment.

Richard Schaffer, Suffolk Democratic chairman, said he had spoken to Rumsey about running several times in the spring, but added that Rumsey had initially indicated he decided against making the race. Schaffer said the party would have been happy to carry Rumsey’s petitions if he had known he was still interested. The party did not circulate a petition for any candidate in the race.
