Voter fraud is arguably the largest threat to our republic. Unless you want a federal voter registry – and I don’t, nor would the Founders – the only way to tackle the problem of illegal voting is to pass an amendment requiring State govt-issued VoterID in all elections.
The use of this can be indirectly mandated via threat of application of the 14th Amendment’s clause to limit representation (House seats, Electoral College votes) as a result of fraudulent voting if this ID is not used.
Amendment wording to require States to issue tamper-resistant photo IDs would prevent States from suing in SCOTUS over the Feds forcing them to spend money implementing this. Issuing these IDs every four years would help reduce voting by dead people, if the issuance is linked to the State death certificate database.
Because a vote is more powerful and dangerous than a gun, a check when issuing an ID against a current citizen database similar to a check against a national database when buying a gun would seem in order. How not to make this a national voter database is a problem to which I assume smarter people than I have a good answer
Formally rejecting Motor-Voter registration, the largest source of non-citizen voting, should be part of this amendment. Because it would be an amendment it can overrule that part of Article 1.
Any amendment dealing with voting also must mandate paper & ink voting. There is no way to prevent fraud in computer voting, no matter what you read. (My career has been in IT for 40 years.) Getting non-fraudulent results later is far better than fraudulent results immediately.
We will never get rid of the problem of “Who watches the Watcher,” but this would go a long way in reducing fraud.
Given the 2016 results, that Trump will be appointing at least 2-3 Justices, that amendments can take time, we need to get on this ASAP.
