Why is this so important?
Because formerly solidly-Democrat regions of the country (much of the South) are in DANGER of turning Republican.
The only way to prevent that is to flood the voting ranks with phony registrations, particularly in dense parts of the states involved. You can't as easily do that if you have to phony up some identification. So, the ID laws slow the "progress" of the Progressive's taking over the state (and, through their domination of the votes at the state level, the federal vote - executive and senatorial).
In some of these states (the Carolinas, for example), MANY non-citizens try to vote - often, they succeed. Other chronic offenders are the "sunbirds" - those seniors that split their time between a Northern state and a Southern one. SOME of them vote twice - once in the summer state, and once in the winter state. Increase in the absentee voting has facilitated that fraud.
Yes, I do call it fraud. In some cases, the senior may not be smart enough to realize that they are committing a crime (their dimness leads some conservatives to believe that these are Democratic voters - not me, but some).
Look for changes to be in effect by the next fall elections. Should be interesting.
