Computerized voting machines and networks INVITE fraud. There is no high tech solution to this. High tech solutions just inspire high tech workarounds.
Low tech is the only solution. Use only hand marked/punched paper ballots and count the ballots with machines that are mechanical (electric motors are OK) and maybe optical, with NO programmable components and NO networking.
“Low tech is the only solution”
We saw low tech during the 2000 hanging chad fiasco. There will be cheating no matter what system is in place. The opposition is immoral and believes the ends justify the means. Wherever they control the local board of elections there will be fraud.
