Edit: I shouldn't say the "entire" Act as some aspects might be untouched but the major relevant portion of regions required to gain approval before **** with the voting abilities of the people there is effectively dead.
I suppose the good that can come out of this is the SCOTUS will have to set precedent on individual voting issues as being discriminatory or not. It just takes a long time for that to happen. In the meantime, many will be disenfranchised.
I think what the republicans aren't fully realizing is that, at least with voter ID laws, friendly fire could take as big a toll on voter turn-out as those being selectively discouraged from voting.
