Don’t think that Florida 2000 is completely behind us. Ohio is a battleground state where the vote could be close, and a number of Ohio counties will be voting with punch card machines. See this USA Today story, this A.P. story and this post by Dan Tokaji entitled “Ohio: An Election-Day Disaster in the Making?”
UPDATE: On my dimpled chad question, Dan Tokaji writes: “The answer is no. Ohio RC 3515.04 requires that at least two corners of the chad be detached: ‘If a county used punch card ballots and if a chad is attached to a punch card ballot by three or four corners, the voter shall be deemed by the board not to have recorded a candidate, question, or issue choice at the particular position on the ballot, and a vote shall not be counted at that particular position on the ballot in the recount.’ The Ohio Revised Code can be found here.”
