Another good candidate for Karl Rove Dirty Tricks Watch.

And here I think we may have a serious contender. Someone in Columbus Ohio seems to be calling voters, impersonating an employee from the local election board, and telling folks that the location of their precincts has been changed. The recipients of the calls seem to be disproportionately elderly.

This one's right out of the Karl Rove playbook. I'm making this the top contender so far, though I'm sure there'll be many more. Of course, maybe I'm not given enough credit to Rove's Sproul operation. Have to give it some thought.
