Reply #270: no, I don't think so

A fair distinction, but I can't find support for either version in the DNC report that is offered as the source. Rather the opposite.

Quoting p. 23 of the DNC report:

"Two (2) percent of voters experienced ballot problems in Ohio. These voters either had trouble receiving their absentee ballots or had their registration status challenged at the polls.... Younger voters and newly registered voters experienced the same proportion of ballot problems as older and previously registered voters."

I can't get from there to "one in every four Ohio citizens who registered to vote in 2004 showed up at the polls only to discover that they were not listed on the rolls." Can you?

(EDIT TO ADD) Here is something that is closer, on p. 30 of the DNC report: based on a survey of 400 provisional-ballot voters in Cuyahoga County, Walter Mebane estimates that 26.5% of new registrants in Cuya cast provisional ballots (with a large degree of uncertainty about the estimate). I don't see any immediate way of telling how many of these were people who hadn't submitted ID when they registered and didn't do so when they voted.
