Individual fraud happens, but at levels so low it essentially never alters outcomes. Systemic election fraud is still rare, but when it happens it tilts elections precisely because it’s systemic.
Secure the system by securing it’s infrastructure. It wasn’t forcing people to show drivers licenses that caught this; it was improvements made to the systems of collecting and recording votes that did.
That the people most interested in stopping fraud by voters would use this instance of fraud by officials to push their unrelated solutions tells you everything you need to know about the sincerity of their arguments. Don’t fall for it.
Fraud by voters isn’t fraud by campaigns and vice versa. Not hard.
