If you canāt understand that thereās nothing I can do to help you. The federal government telling states what to do is the opposite of small government conservatism
Are you referring to elections for federal government positions?
You might want to read up on the subject. Itās really a matter of ensuring that existing laws are upheld. Are you familiar with the āIllegal Immigration Reform and Immigrant Responsibility Act of 1996ā?
You see that is a federal law. How states prove they are compliant with the federal law could be done several different ways and that would be a stateās choice. But it is a state choice of how they ensure they are compliant to the federal law.
Personally, I would agree that fingerprint would be sufficient if there was an instant check and entry into a āvotedā data base. An ID card would work too under the same conditions. But such things must go hand in hand with cross state checks to ensure people donāt vote in multiple states. So interstate cooperation could be involved as well.
Adding to the confusion you have is the fact that several states even have laws against non-citizens voting in state and local elections. And how they enure the law is met would be a state and local decision.
So your Quixotic search for a one-size-fits-all answer is a bit of amusement for a Sunday morning but it does not further the discussion on what āconservativesā believe regarding federal vs state involvement.
