Hillary Rodham Clinton will concede Tuesday night that Barack Obama has the delegates to secure the Democratic nomination, campaign officials said, effectively ending her bid to be the nation's first female president.
Obama is 40 delegates shy of clinching the nomination, but he is widely expected to make up the difference Tuesday with superdelegate support and votes in South Dakota and Montana. Once he reaches the magic number of 2,118, Clinton will acknowledge that he has secured the necessary delegates to be the nominee.
The former first lady will stop short of formally suspending or ending her race in her speech in New York City.
