In 2012, a manure pile was dumped in the same spot several weeks before the election.
No one was arrested at that time.
This time around, Democratic party chairwoman Bethe Goldenfield told BuzzFeed News the pile was cleaned up within a few hours, but the party is still waiting to hear what the cost will be.
"Having this happen again was a disappointment, but we simply had it cleaned up and kept on working with our volunteers and concentrating on getting out our voters," Goldenfield said.
She added the party has received a number of supportive phone calls, as well as new offers from people to volunteer.
"They go low and we hold our head high and keep working to accomplish our goals," she said.
