Washington ? Senate Democratic leader Tom Daschle said Tuesday he will not run for president, even as some staff members were preparing for a weekend announcement of a race for the White House.

“I’m not going to run for president because my passion is right here,” Daschle said during a briefing about the new session of Congress. “I must say I feel as good about this decision as any I’ve ever made. I’m very honored and gratified to have the opportunity to be a Democratic leader.”

The 55-year-old South Dakota lawmaker said he would run for re-election to the Senate in 2004. He also said he may consider running for president in the future.

Daschle had talked enthusiastically about such a race recently, including Sunday night in his home state when he said after a meeting with constituents: “I think it’s fair to say I’m leaning in the direction of offering my candidacy for president.”

Daschle’s announcement means the current field for the 2004 party nomination consists of fellow Sens. John Kerry of Massachusetts and John Edwards of North Carolina, along with Vermont Gov. Howard Dean and former House Democratic leader Dick Gephardt of Missouri. Sen. Joseph Lieberman of Connecticut is expected to enter the race but has not announced a final decision. And the Rev. Al Sharpton of New York has said he plans to run.
