The old-fashioned methods of vote fraud probably work best. No computer technology is required.
You might also notice that "absentee ballots" and "early ballots" provide plenty of opportunities to make the votes come out right. There is no way to know who really cast them - the signature verification procedures are a farce.
I am convinced that this is how we get 105% turnouts for entire counties in this State. They always vote for Democrats by some odd coincidence.
The Clinton/Obama “machine” literally owns the electronic voting machines, because whoever is in office has that control..... the collusion involves not only the MSM but all of the “reliable” pollsters.
That said....the only counter to this is people voting in droves sufficient to counter that.
If you do the math, in our precinct we have about 40 seconds to process each vote. Time polls are open/ number of registered voters. This means no step in the process can take longer. We can improve the throughput by adding voter booths so voters can take several minutes to do a complicated ballot, but the bottlenecks remain at the check in table and the ballot counter. So how is it we are slammed all day to handle a 65% turnout, but the inner city precincts can handle 100% turnout no problem? I suspect a shortcut....
