@Cycloptichorn,
Oh, I don't doubt what the Republicans would like to accomplish with these laws--they have also tried to re-draw the lines of my Congressional district at every opportunity they've had, for similar reasons, to try to reduce Democratic votes.
That still doesn't mean that all the voter ID laws actually prohibit anyone from voting--and the U.S. Supreme Court ruled to that effect in the case of Indiana, where they did not feel the photo ID requirement prevented or prohibited voting.
And, it remains to be seen whether they can make a successful case in Pennsylvania that people would be prohibited or prevented from voting because of this law--particularly since the new voter photo ID card would be available free, and without the requirement of a birth certificate, to those who might otherwise fall through the cracks and be unable to obtain other acceptable photo IDs.
