I've always been a little agnostic on national I.D. cards...similar to a passport. And I don't think there's much hope of passing it anyway.
But two things have caused me to lean more towards such a provision: voter fraud and illegal immigration. I'm becoming more convinced a national I.D. card is the way to go.
I don't see why ANYONE is against a national ID system. Technically all we would be doing is bringing the DOT into the 21 centrary and inter-connecting all the indivual state driver licenses into one.
Thats really all we're talking about.
