Less than 24 hours after Senator John Kerry announced that he would not enter the 2008 presidential race, some of his prominent contributors are joining the camp of Senator Barack Obama.

So far, at least, the list includes: Bob Farmer, who was Mr. Kerry’s chief fundraiser; Mark Gorenberg, Mr. Kerry’s top money man in California; and Alan Solomont, a major fundraiser in New England for Mr. Kerry and a former national finance chairman of the Democratic National Committee.

Orin Kramer, a prominent New York Democratic fundraiser, has also signed on with Mr. Obama.

Democratic officials said Mr. Solomont and Mr. Kramer had both considered backing Senator Hillary Rodham Clinton, but decided to go with Mr. Obama, who announced 10 days ago that he had formed an exploratory committee.

Stay tuned as more Kerry contributors search for their new candidate.
