Well, in a quick search, I couldn't find the actual numbers, but I've heard the number of voter fraud cases is extremely low and nowhere near enough of a problem to warrant the attention that the Republicans are giving it. Now, if this is true, and you take in the the fact that this is going to affect a lot of legitimate voters that would never cast their vote for the Republicans, it's not hard to put two and two together and discern their motivations. And considering we live in an era where politicians don't do any actual governing and simply start campaigning for the next election the moment they are elected, it's not much of a stretch to believe.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
