The third and final member of the York City Council whose term expires Dec. 31 announced Monday that she, too, wants more time on the five-member board.
Renee Nelson's decision means at least five people intend to compete for three seats up for grabs.
Two other incumbents - Henry Nixon and David Satterlee - have said they will seek re-election as Democrats.
Aaron Anderson, the pastor at City Church York, announced last month that he'd be throwing his hat in the ring. He is also a Democrat.
Libertarian Manuel Gomez has also said he intends to run.
Available on the council are two four-year terms and one two-year term.
To get their name on the May 21 primary ballot, Democrats and Republicans can begin collecting signatures Feb. 19. Nomination petitions must be submitted to the York County Office of Elections and Voter Registration by March 12.
Nelson, a Democrat, announced on Twitter that she consulted with family before deciding to seek re-election.
"I have also heard from several taxpayers who have been pleased with my efforts," she said in an email.
She could not be immediately reached for further comment.- Erin James may also be reached at firstname.lastname@example.org.
