There are many comments here pointing out the (quite reasonable) fact that hacking voting machines on a large scale is likely to be discovered and thus unsuccessful in stealing a U.S. Presidential election. Even so, the average voter is quite protective of the idea that American elections are structurally fair (a sentiment that is actively inflamed to imposed voter disenfranchisement schemes, like ID requirements). If the goal is to expose the fundamentally insecure nature of electronic voting in the US (and potential for truly fraudulent election results in tight districts) a complete invalidation of voter ballots [i.e. Big splashy, obviously fraudulent election results] would surely draw enough attention to force some public discussion of investing in secure, auditable voting machines.
