The story

Despite an overwhelming defeat in North Carolina and a narrow victory in Indiana, Sen. Hillary Clinton vowed to stay in the race until her party has a nominee.

"I, obviously, am going to work as hard as I can to become that nominee. That is what I've done; that's what I'm continuing to do," she said Wednesday in Shepherdstown, West Virginia.

The focus of the Democratic race now turns to the superdelegates, because they outnumber the remaining pledged delegates.

Neither Sen. Barack Obama nor Clinton is expected to win the 2,025 delegates needed to capture the nomination during the remaining contests. That means the superdelegates -- party and elected officials who are allowed to vote during the national convention -- will probably decide who becomes the nominee.

Obama is ahead of Clinton in total delegates: 1,842 to 1,686. Watch how the numbers work against Clinton Read full article »
