Democratic front-runner Barack Obama scored a coup Wednesday in his White House nominating battle against Hillary Clinton by winning the high-profile endorsement of blue-collar champion John Edwards.
"I don't believe in quitting. You may not win in life, but you do the best you can. You go the distance," she said, after scooping 20 of West Virginia's 28 delegates on Tuesday.

Obama won the support of at least five more superdelegates Wednesday. Clinton secured the backing of one, a party leader in Tennessee.

Obama was also endorsed by three former chairmen of the Securities and Exchange Commission, who joined ex-Federal Reserve chief Paul Volcker in extolling the Democrat's capacity to take on "monumental economic challenges."

And Clinton, bidding to be the first female president, suffered a body blow with the endorsement of her rival by the million-strong NARAL Pro-Choice America.
