Per KNS:

Davis also argues that in 2008, when a group of citizens filed petitions with the Election Commission to put several Knox County charter changes on the August ballot, that the Election Commission allowed non-registered individuals to sign voter registration applications forms and sign the charter amendment petitions "simultaneously."

So did Davis turn in voter registeration apps for her unregistered petition signers, "simultaneous" with her candidate qualifying petition? The article doesn't say she did..

Also per KNS:

When those individuals signed the charter petition, some became registered voters after the deadline for turning in the charter amendment petitions, Davis argues.

The relevant question here would seem to be whether the Election Commission certified the charter amendment petitions before registering some of the new voters who signed it. Again, the article doesn't comment on whether this happened (but I never before read anything to indicate that it did)...
