A possibly interesting fact about these voter ID laws is that the SCOTUS has been, according to most observers, primed to declare that the section of the Voting Rights Act that requires automatic DOJ review and approval for changes to voting laws in certain states determined to have a prior history of disenfranchisement is no longer needed since so many years have passed since there were intentionally discriminatory voting laws and election rules.
The lawsuits regarding these Voter ID laws give the judges hearing the challenges the opportunity to make factual findings that the GOP lawmakers had discriminatory intent when passing these laws. I think that is a real possibility in the South Carolina case since "smoking gun" e-mails and testimony is in the record before that court.
That would be very interesting and ironic if it turns out that the GOP's overreaching on these voter ID laws for obviously discriminatory motivations ends up disrupting the conservative justice's planned direction on the Voting Rights Act. It would be hard to say that no discrimination has happened in 50 years when federal judges hearing evidence make factual findings that we have present day case(s) of intentionally discriminatory disenfranchisement.
Where Ignorance is Bliss, 'Tis Folly to be Wise.
