Barnes is a U.S. Army veteran who previously worked in budget management for MCI Corporate and also managed operations at Hebestreit Communications and Cellular One.
He previously spoke proudly about being a foster and adoptive parent of two children who will be graduating from Havre de Grace High School, and he said he would like to focus more on family-oriented events in the city, giving families more options and activities.
He believes in fiscal responsibility, a sense of community, putting citizens first and "keeping it green," according to his website. Barnes would try to curb residential sprawl and shore up downtown "mom-and-pop" businesses.
His most prominent role, however, has been as founder of the Havre de Grace Drama Guild, which he has led for the past eight years.
Barnes said that and his experience with the Office on Aging has given him a lot of connections in the community. He also said it was important for him to get his message out, as a newcomer candidate. Barnes expects to put up door hangers this weekend, although he said a lack of donations in a tough economic climate has kept him from doing a full mail drop in Bulle Rock.
"So far, it's been a very positive experience," he said Thursday of the campaign. "Me and Bob, we are kind of like the fresh meat. It's really important for us to get our message out."
"Hopefully everything that I have done shows how much I love Havre de Grace," he said.
Greene, 66, a retired businessman who lives in St. John Towers, is active in a variety of civic activities.
Greene said Thursday he has also been walking around talking to people and gotten in touch with a lot of people he has known over the years.
He said he wants Havre de Grace to be known for civility and is going to write to "people in Washington" to have the city recognized for its government.
"I am going to work to have Havre de Grace proclaimed the nation's capital for civility," he said.
He also said he intends to create a number of non-profits and foundations, and wanted his candidacy to emulate that of former president John F. Kennedy.
"Ask not what your city can do for you; ask what you can do for your city," he said.
Cullum, a Havre de Grace resident since 1968, retired in 2006 as a battalion chief from the Aberdeen Proving Ground Fire Department and has volunteered with the Susquehanna Hose Company since 1969.
He has been on the board of directors for the Maryland Municipal League and the Lower Susquehanna Heritage Greenway.
Cullum, 63, said in previous interviews he has spent 16 years with the city council and said his experience played in to his decision to try to return.
"I think I still have a lot to offer," he said. "I think the city is in good shape financially."
