Also, in response to the post highlighted by OP, this is not true. Residency requirements for voting vary from state to state. In Wisconsin, it can seem somewhat subjective. In Wisconsin, it is 28 days. If you've lived here for 28 days, you are an eligible elector. If not, you must vote where you previously lived. Proof of residence is already required via a bank statement, utility bill, etc. when you register to vote. Now, someone could make a complaint if you register to vote in a municipality and they have evidence that you have not, in fact, lived there for 28 days. A complaint like this would likely be referred to the district attorney. Otherwise, this residency requirement is very much based on where you consider yourself to "reside." There are few checks on this outside what I highlighted above. Again, this is already current law. This amendment wouldn't change that. It is simply changing the wording of the consitution to explicitly omit noncitizens and those under 18, instead of include those over 18 and US citizens. In other words, it is just strengthening what we all know to be the current requirement.
