Ghosts Voted in Rural Ohio?

A poster at Dailykos went to one of the election hearings in Ohio and relates this tale:

An election watcher went over to Pickaway county in Ohio to see what was going on there. She asked to see the polling books which was her right by law. These books show the signatures of all those who are authorized to vote at the polling precinct.

When the poll watcher flipped open the books, she saw that lots of people had been allowed to vote but had not signed the books. This struck her as very odd, of course, since by law people have to sign in to verify that they are authorized to vote.

Soon, the board of elections head in Pickaway came by, took the books away from her, threatened her with arrest. When the woman responded that the Elections supervisor was breaking the law, the supervisor rezponded that Ken Blackwell had just told her to take the books away from the watcher. A couple phone calls had been placed, apparently.

All the panel during the Ohio hearings was shocked by this story. These books are out there, and the signatures cannot be faked. The panel took the testimnoy and promised to follow up.

Wouldn't it be just like Karl Rove and buddies to accuse the Democrats of padding the vote with unauthorized voters, while all the while planning to pad the rural vote in places like Pickaway?

Questions: are the rural conservative voters who came out in droves really just ghosts? Do they exist? And if they exist, did they stay home and did someone else vote for them?
