“At this point that would exclude approximately 60% of our population.”
I read the article. The 60% figure would decrease if they factored out Social Security Retirement Income and Medicare. Those transfer payments were legitimately earned through ongoing payroll taxes for most people. But any unearned benefit, like welfare or medicaid, should be a disqualifier removing a recipient from the voter rolls; even temporarily, due to conflict of interest.
Medicare recipients, especially, are taking far, far more out of the system, on average, than they ever put in. As, of course, are many SS recipients.
I get your point and my leanings are toward tiny-government libertarianism. Just suggesting that most—including many here—would currently be removed from the voter rolls by that criterion.
