Newt Gingrich has floated the idea of people being required to take a test to be able to vote. This eerily reminds me of civil rights era times where many African Americans could not vote because of poll taxes or hard as nails poll tests. Both of those tactics, along with KKK strong arming, were meant to keep African Americans away from voting. The South is still recovering.
Gingrich may be sincere, but with a PhD you would think he would know how sensitive this issue is to the fabric of America.
