The federal government on Friday told election officials in 21 states that hackers targeted their systems last year, although in most cases the systems were not breached.
Uh, "most" weren't breached, which means "some" were... were votes changed?
Other stories indicate that attacks were on voter registration systems rather than the voting systems themselves. As a former poll judge, I can easily say that that's the attack surface you gotta worry about. If you don't have an accurate voter roll even the dead can vote perhaps repeatedly in that Chicago way.
