I see stories about how election is rigged or that there are security vulnerabilities and lots of people don’t believe the outcome. Why don’t they just open source everything so that anyone can look at the code and be sure the votes are tallied correctly?
We use paper ballots that are scanned by machines and then kept if needed to check or recount.
Not every state does this, and it’s ultimately up to each state how votes are done. The federal government actually has very little say in how states handle elections.
