I think ACORN played it’s part. But, I think they perfected the art of digital fraud with this election.
Whether it was ACORN or one or several of the ACORN-like organizations under different names, you raise a very important point with digital fraud, which definitely seems to be a major part of the 'Rat cheating scenario, and one which was not so apparent several years ago.
Digital fraud requires a level of technical expertise which seemingly wasn't as apparent in the fraud operation of 2008. It required the integration into the Obama campaign apparatus of a cadre of bright but sinister and corrupt operatives who were capable of hacking into the electronic vote counting and/or tabulating systems. At least some of the optical scanning systems used by county election officials, especially those manufactured by Diebold and its successor corporation, had been pretty well known to be vulnerable to hacking for the past decade or so, with documented incidents in local elections in large south Florida counties. Vulnerable to hacking also are some touch screen voting systems, as reported by voters who voted for Romney in Colorado, yet were informed by the computer that their vote was counted for Obama.
The bottom line is that state legislatures have to get to work to see to it that all electronic voting equipment used anywhere in their states is carefully inspected by computer engineers to assure reliability, accuracy, and security from hacking. If government can inspect other contracted equipment serving other government functions to assure that the product is reliable and safe (e.g., military equipment), it should be forced by Americans willing to protect the integrity of their voting rights into doing the same for electronic voting equipment. And if it can't, we can forget about about electronic equipment altogether and go back to paper ballots visually inspected by reps of all candidates. Integrity in vote counting is more important than speed!
