A quick look around town will show you who developers are supporting in next week’s Democratic primary. Campaign signs appear in the windows and on the buildings of several properties owned by developers: the sales office of SkyView at Carriage City Plaza (above) and the former Dornoch offices (still owned by Dornoch) at 1513 Main St. (right).

and the building on the corner of East Milton Avenue and Main Street (below), purchased in 2008 by Landmark Companies, which is building Park Square, the 159-unit rental project at Elizabeth Avenue and Irving Street. CORRECTION: I’ve been told the space the corner of East Milton and Main was rented by the Proctor campaign and is not an endorsement by Landmark.

The June 8 primary will be the city’s first contested primary in about 20 years. City Health Officer Rick Proctor, also a county freeholder and the municipal Democratic chairman, got the backing of the local party, while former Housing Authority chairwoman Renee Thrash is running off the line. Three at-large council seats are up, with incumbents James Baker, Sal Mione and Nancy Saliga challenged by Yvonne Wesley, Lynn Parker and Grace Jacquet. The Republican primary is uncontested, with local GOP chairman Patrick Cassio running for mayor with council at-large candidates James Grady, Kevin Retcho and Jeff Spatola.

Mayor James Kennedy, a Democrat, decided not to seek re-election this year after five, four-year terms. He plans to remain as unpaid executive director of the nonprofit Rahway Arts District, which now receives funding generated by the Special Improvement District (SID).
