Hillary Clinton eyed a landslide in Tuesday's West Virginia primary, but was unlikely to break Barack Obama's stranglehold on the Democratic nominaton. The former first lady, vowing to battle on even as Obama turns his sights on Republican presumptive nominee Senator John McCain, led her foe by 36 points in the latest poll out of the mountainous state. "West Virginia has a record of picking presidents," Clinton said in a campaign stop here, as she pressed home her claim that she, and not Democratic foe Barack Obama was the best Democratic White House pick. "A Democrat doesn't win the White House without winning West Virginia. So tomorrow it's going to be your turn."
