OTOH, he does have a point. Manhattan couldn't have an election while dealing with the aftermath and New York postponed the primary scheduled for that day. So if we did have an 11/2 attack we'd be faced with having to postpone the election or having a chunk of the country not vote that day.
t3knomanser came up with a very good idea for how to handle the problem: Have everyone vote absentee. This also fixes all the hanging chad, electronic voting machine, and access to polling stations problems I've heard so much bitching about. And it does it without needing any new rules or equipment. We would need a lot more manpower to count them, but the poll station staffers would be available, and that's a lot of man-hours.
There's some personal appeal too. I could fill out the ballot, seal the envelope, vomit, mail it off, and then stick my fingers in my ears and ignore the rest of the electoral fracas until the counting starts. That'd be nice. Maybe I'll vote absentee this year anyway.
