That sound very plausible to me, the point is, however what we can do about it. One simple solution is to boycott the voting machines altogether and request absentee ballots, which do leave a paper trail.
If enough people request absentee ballots, it would make the electronic fix more obvious, as they would have to electronically create more "votes" to counter-balance those cast via absentee ballots. An added bonus of this tactic is spoofing TV spin doctors and the media hoopla that accompany the election. Absentee ballot results will be tallied several days after the election.
