"The rate of valid ballots is typically < 20%."
It was late last night, but I think I remember Ken Blackwell, the Sec. State of Ohio, saying that in the past they had validated about 90% of provisional ballots.
Anyone else remember that interview on Fox?
I was there with you--he did say that in the past only 10% were tossed out. HOWEVER, he also did say that he felt the provisionals would break ever so slightly for Bush. In other words, a wash.
