No. I know that most major points have already been covered. But here're my 2 cents in a nutshell: 1. An online actions can never be as secret/anonymous as a physical actions. This much we've definitely learned from all the recent surveillance news. Obviously ballot secrecy is critical to fair elections. 2. Online ballots would be much more suspectible to manipulation than physical ballots would ever be. If a private contractor were hired to do this (i.e., how current election software are already commissioned), detection of manipulation would be difficult, and accountability difficult to ensure. 3. There would be the problem of authentication, as others have pointed out. This would make the recount process even more contentious and uncertain than it is now.
