A tiny Catskills resort town is playing host to a federal probe over voter fraud accusations — even as locals head to the polls next week, The Post has learned.

Residents of Fleischmanns — a century-old “Borscht Belt” village located at the foot of the Belleayre ski resort — claim that a pair of deep-pocketed property moguls have recruited seasonal renters to stuff the ballot box so they can get favorable treatment for their development plans, as The Post previously reported.

Following repeated voter fraud disputes in Delaware County during the past two years, the local sheriff once again is investigating 76 voter registration cards — a big number given the small size of the expected tally — that were submitted during the past month, sources said.
