Incumbents seem to rule in the hours before nomination papers are due in three Island towns.

With just one full working day left before contestants for elected office must file nominating papers, town clerks in Edgartown, West Tisbury and Oak Bluffs report that all races are so far uncontested and many races have no candidates at all.

After 5 p.m. Thursday, anyone who plans to run for office in those towns must do so as a write-in candidate.

“It is not a contested year and the candidates are all back. They all seem to want to continue to fulfill their job,” said West Tisbury town clerk Tara J. Whiting. All of the incumbents are running unopposed for reelection, including selectmen Cynthia Mitchell, she said.

Meanwhile, Oak Bluffs may be in need of candidates. All three members of the finance committee — Bill McGrath, Robert Blythe and Michael Taus — have reached the end of their terms. But so far only Michael Taus and a new candidate, James Klinginsmith, have filed papers, Oak Bluffs assistant town clerk Laura Johnston said.

Planning board member Mark Wallace and school committee member Lisa Reagan, both at the end of their terms, have also not yet filed papers.

Incumbent selectmen Gail Barmakian is running unopposed.

In Edgartown, finance advisory committee members Steven C. Jordan and Fred Condon and planning board member Robert M. Cavallo have not yet filed papers for re-election, leaving those races potentially without candidates.

Glenn Searle is running unopposed for election on the park commission to fill a seat left by Christopher Dolby.

There is an opening on the wastewater commission left by Cliff Karako, who has resigned.

Wastewater moderator Duncan Ross has not yet filed papers for that position, nor has anyone else.

Candidates in the other Island towns still have time to mull their political futures. The deadline for filing nomination papers in Tisbury is March 12. In Chilmark, the deadline is March 27 and in Aquinnah it is April 10.
