Who returned 70 unsigned absentee ballots in Ohio?

Cross-posted from Election Journal, your source for election fraud information.

The Dayton Daily News reports that Miami County election officials are trying to figure out how 70 unsigned, but otherwise voted, absentee ballots were returned to the board of elections:

Miami County election officials Friday, Oct. 31, asked prosecutors and the sheriff’s office to investigate suspected voter fraud involving at least 70 absentee ballots.Elections Director Steve Quillen said elections staff began asking questions about absentee ballots previously set aside when several voters complained they had not received their ballots. The ballots were set aside because their envelopes were not signed by the recipients.

These were requested absentee ballots that never made it to their voters but were returned anyways. Quillen notes that they all went out through the same post office:

Quillen said absentee ballots are left at the Troy post office, where officials said they then go to Dayton for processing and return to the county for delivery.

Dare I note that the American Postal Workers Union, an affiliate of the AFL-CIO, endorsed Barack Obama?
