The point at which a black person becomes the POTUS. At that point, it's no longer possible to say that blacks can't rise to the same level as whites.
Not to mention the many black cabinet members, chiefs of staff, congressmen, senators, etc...
No, the time for affirmative action and racial favoratism is over. 50 years ago was 50 years ago. The same artificial barriers no longer exist. To claim otherwise is nothing more than white guilt, and you should be ashamed of yourself.
I'm going to agree with you as far as the federal positions you have mentioned are concerned. However, it's at the state level that the VRA is, IMO, still needed, due to the numerous and blatant disnefranchisement and suppression tactics that many Repub controlled states (North and South) are attempting to or have passed in their state legislatures.
It seems to me the pattern that has been followed by many State Repub leaderships have been to use gerrymandering to lock in a majority in their legislatures/administrations and then proceed to further disadvantage their opposition through the use of the aforementioned disinfranchisement and suppression tactics in Dem heavy districts of which they can't acquire through gerrymandering. This is an excellent way for a minority party to defeat the opposition majority, something that given the current demographic trends, the Repubs will have to resort to to win future elections. If that ain't violating the intent of the VRA I don't know what is.
Getting rid of the VRA is a fairly obvious tactic that curiously, only the Repub state leaderships favor and more curiously, it just so happens that (correct me if I'm wrong) only Repub controlled states are required to comply with that Act, which, in and of itself is indicative of malfeasance on their part.
Looking at the larger picture, getting rid of the VRA fits in quite nicely with the overall Repub strategery for keeping control of their state governments even though in most cases they are eventually going to be the minority party.
Given the former, I'm going to have to conclude that to ignore the widespread use of these tactics at the state level to argue for the demise of the VRA just doesn't make a bit of sense.
