You may be right, Ted. My understanding is that what they were saying is that no Democrat has won the White House in a long time without winning West Virginia in the general election. That still is a fair point, since the results show Obama is not very likely to win WV in the fall.
The exit pollint data is somewhat troubling for the campaign in the general election. However, this is not going to effect the outcome of the Democratic nomination.
Now if Hillary had upset Obama last week in NC, it would have been entirely different - the Democratic party would today be shaken to its core; a few good, hard blows struck in the right places might have been able to split it wide open. (Ah, what might have been :-)
As it is, IMO Obama will be the nominee, Hillary will at least unofficially concede in the June 4-13 time frame, and the party will united behind Obama who will go into the fall the favorite - but weakened enough that it will still be a horse race.
