This story has been modified to add that Ward 1 Councilor Lisa Tully is not seeking re-election.

PITTSFIELD — The first one in is also the first one out.

Citing an increase in business and travel commitments, Ty Allan Jackson will not seek an at-large seat on City Council.

In February, just days after at-large Councilwoman Kathleen Amuso announced she would not seek re-election, Jackson had announced his intent to run.

His decision to step away was announced via his Facebook campaign page Monday afternoon.

"This wonderful city deserves council members who are going to give their all for the betterment of our city and I realized with my constant travel I would not be able to serve in the manner in which I prefer," the statement read.

The author and entrepreneur credited coverage of his books on CNN and NBC with a spike in speaking engagements requests from across the country.

"This is now the opportune time to take advantage of that national press," he said in a telephone interview. "It would be unfair for my business, as well as the city of Pittsfield to try and pursue both."

Jackson, who had the support of Mayor Linda M. Tyer, Amuso and others, said he was not ready to endorse any other candidates for council.

"I want to see more of who will be throwing their names in the hat," he said.

With the exception of Amuso and Ward 1 Councilor Lisa Tully, incumbents on both the council and the School Committee have said they intend to seek re-election. And there are potential challengers for all seats, with the exception of Ward 7.

All those who have taken out nomination papers who have not been reported on thus far have either declined The Eagle's interview requests or could not be reached for comment.

Nomination papers are due to the City Clerk by July 24. Once signatures are certified legitimate registered voters, candidates have until Aug. 9 to withdraw from a race.

If a candidate qualifies for more than one race, they need to choose one to run for. A person cannot appear on the ballot more than once during a given election, according to city law.
