Probably better correlation is we let people vote and have access to government largess. It ought to be one or the other - then the stupidity factor becomes less important, probably irrelevant. IOW, there have always been stupid voters.
I agree with you. In fact this was my father’s solution first told to me sometime in the 1980s: Anyone who is on welfare or receives any Federal money that is not expected to be payed back does not vote. Period.
