"Not dropping out would mean ruining the party," the civil rights leader told New York 1 television on Thursday night. "I think Barack Obama's the nominee. I think he's won. The majority of Democrats have already decided."

Sharpton, a failed Democratic candidate in 2004, has yet to endorse any candidate for the November election though he has been actively courted by Obama and Clinton.

He has natural ties to both Democratic candidates: his National Action Network is based in New York City and Clinton is a U.S. senator from New York state. And he has also championed causes for African Americans, and if elected Obama, a senator from Illinois, would be America's first black president.

But his latest words suggest an endorsement might not be necessary in the nomination battle.

"As you know, I've been in the ministry of civil rights all my life, but had dealings with entertainers because of James Brown," Sharpton said. "The worst thing in the world is when an entertainer doesn't know when the show is over. The audience is gone, the lights are down, you're getting ready to cut the mics off and you are still on the stage singing. It's over, it's all right, it's over. Come sing another day, but this show is over for Sen. Clinton."

Alma Rangel -- the wife of Rep. Charlie Rangel, an indefatigable Clinton supporter and the dean of Harlem politics -- is backing Obama.

"I believe Barack Obama has the ability to unify this country and the character to stand up for what's right instead of what's popular," she said in a statement e-mailed by the Obama campaign on Friday.

The Clinton-or-Obama debate has been trying for many African-Americans who remember Bill Clinton's presidency fondly but also know that Obama would be the first black president.

Underscoring his commitment to the black community, Bill Clinton opened his foundation's office on the main Harlem artery of 125th Street, the same street as Rangel's congressional office and the historic Apollo Theater, where Obama held a campaign rally in November.

The Rangels are not the first political family divided by the race.

Obama has won the endorsement of Massachusetts Sen. Ted Kennedy, brother to the late President John F. Kennedy, a Democratic hero. He also won the backing of JFK's daughter Caroline Kennedy, who called Obama the heir her father's legacy.

But her cousins, Kathleen Kennedy Townsend, Robert F. Kennedy Jr. and Kerry Kennedy announced that they are in the Clinton camp.

In 2000, Clinton won the former senate seat of Daniel Patrick Moynihan, a strong supporter of hers. On Thursday, his widow Elizabeth Moynihan declared herself an Obama backer.
