I'm not a lawyer and I don't know details of Delaware, but it seems to me that she's still playing fast and loose with things.
It seems to me that Delaware uses the term "permanent residence" for where voter registration should be. For example, Title 15 § 1704(c)(3) seems to try to confirm this: "Certify that the address at which they are currently registered to vote is their correct address and place of permanent residence." (my emphasis)
So is she falsifying her permanent residence or what?! There seem to be procedures for keeping the voter registration address confidential, so it seems she could have done that legally.
It's amusing to watch the spinning, though.
BTW, I'm all in favor of personal privacy. I just have a problem with her questionable veracity.
The procedure Christine O’Donnell used is the correct procedure to keep her address confidential.
And, her actual residence is in the same voting precinct.
So she is eligible to vote in that precinct. She resides in the same precinct, but NOT at 1242 Presidential Drive.
And she disclosed this to officials when registering.
