According to this story, Hillary Clinton will concede that Obama has enough delegates to secure the nomination for the democratic presidential candidate:
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. [...]
The advisers said Clinton has made a strategic decision to not formally end her campaign, giving her leverage to negotiate with Obama on various matters including a possible vice presidential nomination for her. She also wants to press him on issues he should focus on in the fall, such as health care.
How much leverage should she have though if Obama has secured a necessary and sufficient number of delegates? Presumably she will have leverage via her supporters and Obama’s need to make nice with them. But if this is true:
A tsunami of superdelegates is poised to rush to Sen. Barack Obama (D-Ill.) over the next 12 hours, giving him a mathematical lock on his partyâ€™s presidential nomination.
The superdelegate surge is likely to swamp a few holdouts within the camp of Sen. Hillary Rodham Clinton (D-Ill.) who have been resisting a prompt concession.
Then Clinton isn’t really doing Obama any kind of “favor,” nor can she say she is conceding out of good will for the democratic party, since she won’t have an f’n choice anyway. Or am I being uncharitable here? The last report continues:
Aides say Clinton does not plan to concede or bid supporters farewell when she speaks in New York tonight, but instead will salute her supporters and argue for the strength of her candidacy.
But her clout is ebbing by the hour. At 6:56 a.m. Eastern time, the Obama campaign announced the first of the dayâ€™s slew of endorsements by superdelegates â€“ the Democratic Party officials who have a vote on the nominee and will determine who it is, since neither Obama nor Clinton have won enough delegates in primaries and caucuses to put them over the top.
