This will never happen, but what if a small requirement be made that any American who wants to vote must first pass a knowledge test. There are many who don’t know squat about this country or what is happening.
Electronically of course; simple questions. Who is the current president? Who is the current vice president, secretary of state, defense, etc. – and who is running against the president.
For regional or local elections, the same questions but modified to reflect those seeking re-election and those running against the incumbent. Perhaps include even one or two questions oflocal, regional or national importance.
Those who fail the short test would have to come back after some study.
