The deck is stacked and the game is rigged.
First link is about someone on parole voting, when they can’t.
Second link is about someone who got caught when trying to do fraudulent voting activities.
The third link is a person with a prior felony conviction (that she pleaded guilty to), that is ineligible to seek office, trying to seek office/vote.
Those are three one-offs, in the margins. None of those prevent the system from working overall.
You’re grasping at straws.
Actually, I’ve voted in every election I was asked to.
