That's why NC passed the law. NC had basically the same law and it encouraged voter fraud which the vote fraudsters take full advantage of. Everybody knew it, but nothing could be done about it until we elected a Republican Senate and Legislature and in 2012 a Republican Governor.
Starting with the implementation of the law in 2016, it will be twice as tough to win as a Democrat as this cancels out many of their fraudulent votes - unless you count the voting machine fraud, which happened in 2012, on the Presidential ballot line (all in Obama's favor, but fortunately just short of "enough" to swing NC into the Obama camp).
Now that the jig is up (pun intended), Holder wants to shut down the new safeguards. The slimy rat should be prosecuted for subornation of voter fraud and wasting taxpayer monies on frivolous lawsuits.
However, short-term, I see one of two things happening, neither of which I like much. NC has been very nearly a 50-50 split at the national level, so either....
1) The state remains a 50-50 split, which shows that there wasn't much fraud and Dems have made dramatic inroads into the electorate over the past 8-10 years. That's bad, IMO.
or 2) The state goes back to what it was before, 55-45 plus or minus a bit. That means fraud has cancelled out my vote for the past few elections.
Neither option makes me very excited.
