On the other hand, the tried and true methods used to corrupt all the other systems, most particularly the PAPER ballot systems, are still quite useable and well known.
This guy in California is just trying to preserve Democratic party dominance ~ nothing more to it than that. If you think any Democrat is concerned with the integrity of any voting system, you are confused.
You can find some examples of non-hypothetical fraud if you do a Google search. Electronic voting machines have only recently started to be used in large numbers, so the problems are mostly prospective, but that doesn't diminish their reality. A simple Google search will also show you the dangers associated with pure electronic voting.
I have no problem with touch screens or electronic voting systems as long as they have a paper trail or other tangible safeguards. Without that, there's absolutely no protection against someone (either an outsider or insider) hacking in and altering the results. Without that, there's absolutely no protection if power is lost or data files are corrupted.
You need to get beyond your partisan blinders and recognize that in this instance the California Secretary of State is doing the right thing to protect the integrity of the voting process.
