As usual, the best summary of this all-too-serious issue comes from John Stewart and The Daily Show:

In response, I have not seen any Republican state legislator present evidence indicating that these new laws are actually needed and will not disenfranchise potentially large numbers of eligible voters. More troubling still, courts have so far upheld every one of these new laws despite (a) the complete lack of evidence that the "problem" they are ostensibly designed to control is real, and (b) substantial evidence that eligible voters are being disenfranchised.
At least the Republican legislator from Pennsylvania, in the Daily Show clip, was being honest about what these efforts are really all about: securing the election of Republicans by undermining the democratic process. Perhaps the effect will only be marginal, but in a close election even a marginal effect may be enough to swing a swing state.
