Clinton Beats Obama in West Virginia

"With a record turnout expected in today's primary, West Virginia Democrats will make clear who they believe is the strongest candidate to take on Sen. McCain in the fall," reads a memo released by Clinton's campaign Tuesday afternoon. The memo also notes that no Democrat in the last 90 years has won the White House without carrying West Virginia.

"I think Democrats across the country tomorrow will be asking themselves why Senator Obama -- with all of his money, with all of the great press, with voters being told he was the inevitable nominee -- why did Senator Obama lose West Virginia by 15 points or so?" Clinton communications director Howard Wolfson asked on NBC's "Today" show.

Regardless of whether they believe she can win, Democratic voters seem content to let Clinton remain in the race through the end of the nomination fight. Nearly two-thirds of Democratic voters said Clinton should stay in the race in a recent Washington Post/ABC News survey, and almost 80 percent of West Virginia echoed that sentiment in exit polling, according to Fox News Channel.

West Virginia is one of just six contests left in the Democratic nomination fight. Kentucky and Oregon will cast ballots next Tuesday, while Puerto Rico will hold its primary on June 1. South Dakota and Montana will close out the campaign on June 3.
