Mashpee Town Clerk Deborah Dami says O’Hara is weighing his options.
If he pursues a recount, O’Hara will have to present 10 to 15 signatures from each of the five Mashpee precincts to the Town Clerk before the deadline.
O’Hara did pull papers to request a recount, according to Dami.
Dami says O’Hara has until Tuesday to file the paperwork with required signatures.
