The issue is the fraud cannot be undone. Unlike your IRS taxes online, there is no IRS to audit trail the vote. And even if there were (cost/privacy logistics aside), the harm is irreprable. If the wrong guy is given power for 2-3 years, its too late to then switch over (justice delayed=justice denied). That is the nutshel of why this "obvious" idea is fatally flawed, IMHO. You are concentrating political power in a black-box not subject to checks/balances, etc. Odd, but paper ballots are the simpler/smarter choice. We just need to lose the clowns administering the elections. Perhaps this should be handed off to a the judiciary or something? Dunno. A good Compromise seems to be (1) national holiday to vote (to increase turnout); (2) IDs (to maintain semblance of legitimacy); (3) simple paper ballot (secure, private, verifiable); (4) computerized registration (to ensure any problems sorted out in advance re(#2).
