After serving 16 years in office, Pottawatomie/Lincoln County District Attorney Richard Smothermon confirmed Monday he doesn't plan to seek re-election to another four-year term.

After serving 16 years in office, Pottawatomie/Lincoln County District Attorney Richard Smothermon confirmed Monday he doesn't plan to seek re-election to another four-year term.

The filing period for that seat and many other elections is coming up in April.

Smothermon, who said he will be eligible to retire in September 2020, believes it would be selfish to run for another four-year term when his retirement date would fall in the middle of that term.

“I can't ask for the public to vote me in four years with the very real possibility I would only serve 18 months,” Smothermon said about seeking a fifth term.

If he were re-elected and retired mid-term, the Governor would have to appoint another district attorney to finish his term. Smothermon said he feels voters should decide who will serve in that office for the next four years.

Smothermon, who first took office as Pottawatomie County's district attorney in 2003, told his staff about his decision on Monday.

The candidate filing period for this seat as well as other state, federal and legislative seats up for election in 2018, is scheduled April 11-13, with the primary election set for June 26.

Reports indicate Smothermon's First Assistant District Attorney, Adam Panter, is a potential candidate, although no formal announcements have been made.

Shawnee Attorney Allan Grubb, through a Facebook page, has already announced that he plans to run for the seat.
