Why, cause one's black? Have you ever seen Ken Blackwell?
Ok, here:
Blackwell also announced he would enforce an Ohio State election law decreeing that any person who appeared at a polling place to vote but whose registration could not be confirmed would be given only a provisional ballot; if it were later determined that the person had attempted to vote in the wrong precinct, then their provisional ballot would not be counted. He also directed poll workers to refuse to distribute provisional ballots unless they were satisfied as to the voter's residence. The Democratic party promptly filed a lawsuit claiming that the policy was "intended to disenfranchise minority voters" and in violation of federal election law, specifically section 302 of the Help America Vote Act (HAVA).[33]
On October 21, 2004, U.S. District Court Judge James G. Carr issued an order rejecting Blackwell's policy.[34] Blackwell said that he would go to jail rather than comply.
Blackwell appealed the decision to the United States Court of Appeals for the Sixth Circuit. On October 26, 2004 the Court of Appeals unanimously affirmed in part and reversed in part. The court agreed with the plaintiffs and the District Court that Blackwell's directive violated HAVA to the extent that it empowered poll workers to withhold a provisional ballot based on their "on-the-spot determination at the polling place".
