Farewell, Primaries. Farewell, Hillary.

From the NYT:

Senator Hillary Rodham Clinton invited fund-raisers and other supporters to an election-night rally in New York City where, aides said, she was prepared to deliver what they described as a farewell speech that summed up the case for her candidacy. They said Mrs. Clinton was not likely to withdraw from the race on Tuesday night, probably waiting until later in the week, once Mr. Obama’s victory appeared clear.

Sensing an opportunity to shut down the nominating contest, Obama campaign advisers said that they were orchestrating an endorsement of Mr. Obama by at least eight Senate and House members who had pledged to remain uncommitted until the primaries ended, and that the endorsements would come the moment the South Dakota polls closed on Tuesday night.

UPDATE: From AP

WASHINGTON — 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.

She will pledge to continue to speak out on issues like health care. But for all intents and purposes, the two senior officials said, the campaign is over.

UPDATE II: Hillary camp doesn't like the word "concede."
