But, rrc has a point about voters requiring something to identify them, even if the reason for the license was problematic. The current system allows fraud which could affect close elections. I don't like the idea of a national ID, nor mark on the head or hand, but maybe just a picture of a registered voter and a date of the picture taken.

I reread rrc's comment, which seems could be interpreted as both ways; either to advocate requirement of positive identification to vote, or to require voters to take an exam to be licensed as a voter, which is what I believe what was meant.

regardless, literacy tests were done before, see http://en.wikipedia.org/wiki/Literacy_test and http://en.wikipedia.org/wiki/Jim_Crow_laws for a background of our (shameful) past.
