It is unlawful for a non-citizen to vote in our elections. Without a voter ID, it will be impossible to prove this violation. There should be someone posted outside of every election polling center and have them see if they can detect any citizenship violations. If so, then all the votes at that particular polling site would be voided. Do that enough times and everyone will get on board with a voter ID. The Constitution states that ONLY American citizens may vote in our elections.
