WASHINGTON, May 14 (UPI) -- Sen. Hillary Clinton's landslide victory over Sen. Barack Obama in the West Virginia primary Tuesday brings her no closer to winning the Democratic presidential nomination, but it is still a major blow for Obama.

The Democrats' Iron Woman has rusted badly, but she still packs a punch.

Clinton, D-N.Y., trounced Obama, D-Ill., by a far wider margin in West Virginia than he managed over her in North Carolina and confirmed the Democrats' nightmare that two of their biggest traditional constituencies that they must mobilize to win the presidency in November -- black voters and white working-class voters -- are now at odds.

Obama beat Clinton in North Carolina by 14 points -- a figure that was widely reported as a landslide. But in white working-class, hardscrabble West Virginia, Clinton annihilated him by 67 percent of the vote to 26 percent, a victory margin of 41 points.

It should also be remembered that despite the Obama campaign's tactical skill at sweeping the Democratic caucuses across the United States, Clinton has hammered him in almost every major industrial and large-population state except for his home state of Illinois and neighboring Wisconsin.
