Me and Tim Robbins BOTH:
I voted as a Democrat in the primaries on Super Tuesday just a few months ago, and I show up to vote today...and I wasn't on the list. Fortunately, someone who lives in my building was working the polling station and was as confounded as I was. Still, I had to vote by affadavit - signing an affadavit envelope and sealing my ballot inside. The lady who lives in my building told me to write the NY Board of Elections a note basically saying "WTF!?" (but really saying that I voted in the primaries and was on the list then and my address hasn't changed since then so there's no reason I shouldn't be on the list of registered voters now). Oy, at least I don't live in a battleground state.
PS My grandma lives around the corner from Obama (in Hyde Park, Chicago)!
