It's election night, and early returns suggest trouble for the incumbent. Then, mysteriously, the vote count stops and observers from the challenger's campaign see employees of a voting-machine company, one wearing a badge that identifies him as a county official, typing instructions at computers with access to the vote-tabulating software.
When the count resumes, the incumbent pulls ahead. The challenger demands an investigation. But there are no ballots to recount, and election officials allied with the incumbent refuse to release data that could shed light on whether there was tampering with the electronic records.
Can't count the votes right, folks, if you can't see them. It's as simple as that.
