In the early hours of Saturday morning, a large truck pulled into a parking lot in Lebanon, Ohio. It then dumped heaps of manure in front of the Warren County Democratic Party headquarters.

"What reasonable person thinks this is OK????" said Bethe Goldenfield, chairwoman of the Warren County Democratic Party, in an Oct. 29 Facebook post that alerted members and media to the heap.

Warren County, which sits northeast of Cincinnati, is overwhelmingly Republican. Voters in the suburban county haven't elected a Democrat to a countywide office since 1976.

Goldenfield told the Cincinnati Enquirer newspaper that the Warren County Sheriff's Office called her Saturday around 7:45 a.m. to tell her about the manure pile. Deputies are now reviewing surveillance video caught by the building's cameras, she said.

Jeff Monroe, chairman of the Warren County Republican Party, told the Enquirer that the GOP was not involved with the manure dump and had offered to help clean up the mess.

Monroe and Goldenfield did not immediately return Mashable's requests for comment. The Warren County Sheriff's Office was not available for media calls on Sunday evening.

The Warren County office has been successful in generating a strong turnout from Democrats since early voting began in the county on Oct. 12, said David Pepper, chairman of the Ohio Democratic Party, via Twitter.

"Lesson: keep organizing while they [bullshit]," Pepper tweeted with a nod to the Democrats' opponents.

Saturday's manure incident follows a more aggressive attack on a local GOP headquarters in Hillsborough, North Carolina, earlier this month.

The Orange County Republican Party office was firebombed and sprayed with graffiti on the night of Oct. 15. A man is now facing felony charges for allegedly making a bomb threat against the GOP office just days before the incident.
