The author seems to be an academic who interviewed people in the establishment who may not personally be crooked; but don’t want to admit the flaws. And most of those flaws are not in the ballot or computers.
Most of the flaws are in lying, cheating humans.
The author seems to have no experience in the real world.
He seems to have no experience in real precincts, nor in real counting rooms. Most importantly, he seems to have no real experience with how Sen Dodd’s HAVA-Help America Vote Act has shaped the computer hardware and software since 2001.
When a party have controlled a city for generations they have all their cronies, relatives and friends working in city hall. They are nothing but a political mafia. They know many ways to cheat and if they have to they can have ballots that have been filled out ahead of time .
If you have no shame, the world is yours.
