When those laws were passed, there were enough leftist crooks to pass them. The root of the problem is the lack of old fashioned American morality.
The problem is that there are now, or soon will be, sufficient leftist crooks in other states to also pass voter suppression laws like those in Caliph-phony-a. Before you know it, there will be enough crooked Democrat states to add up to more than 270 electoral votes, and the country might as well pack it in, or get the guns ablazin'.
