It's interesting...here in Maryland, they don't require me to show an ID...they ask my name, ask for me to recite the correct address & birthday, check it off on the list, and allow me to vote. If anyone else claimed to be me, they'd need to know stuff that few would know.

I suppose if anyone got that far, my vote 'might' be compromised...and I have never been told "No, you already voted".
