There has been plenty of activity prior today's proceedings. According to a story on The Huffington Post, "state officials conceded that they had no evidence of prior in-person voter fraud, or even any reason to believe that such crimes would occur with more frequency if a voter ID law wasn't in effect."
Odd, since that's one of the core arguments for supporters of the measure. It's also interesting that in the past week or so, there's been a lot of chatter about a report on possible voting "irregularities" in Philadelphia.
And, in the end, it may not matter because the U.S. Department of Justice is investigating to see if the law complies with federal law.
Bottom line, the Commonwealth Court will likely not have the last word, so stay tuned.
