NEW YORK (AP) – Senator Biden, Democrat of Delaware,who has made no secret of his plans to run for president in 2008, says he’ll make it official next Wednesday.

The 64-year-old Delaware lawmaker said he will file paperwork with the Federal Election Commission and launch a campaign Web site, http://www.joebiden.com

He joins a crowded Democratic field dominated thus far by Senator Clinton, Democrat of New York and Senator Obama, Democrat of Illinois. Other candidates include Senator Edwards, the 2004 vice presidential nominee; Senator Dodd of Connecticut, Governor Richardson pf New Mexico, Mr. Vilsack, the former Governor of Iowa and Dennis Kucinich, a Democratic Representative from Ohio.

Mr. Biden traveled extensively last year to the early voting states of Iowa, New Hampshire and South Carolina and plans another swing through those states soon after launching his presidential committee, his spokesman, Larry Rasky, said.

Recently, as the new chairman of the Senate Foreign Relations Committee, Mr. Biden convened several weeks of high-profile hearings on the Iraq war.

Generally regarded as a longshot in the presidential contest, Mr. Biden is one of his party’s leading spokesmen on foreign affairs and plans to stress that expertise on the campaign trail. Mr. Biden voted in 2002 to authorize military intervention in Iraq, but has since become a vociferous critic of the conflict.

Mr. Biden has also criticized President Bush’s plan to deploy an additional 21,500 troops to try and stabilize Iraq’s capital city, Baghdad. On Wednesday, the Foreign Relations Committee approved a resolution he co-authored with Senator Levin, Democrat of Michigan and Senator Hagel, Republican of Nebraska, stating that sending more troops into Iraq is “not in the national interest.”

Mr. Biden has also been promoting a detailed plan for peace in Iraq that would divide the country along ethnic lines.

This is not the first time Mr. Biden has sought the presidency. He was a candidate for the 1988 Democratic presidential nomination, but withdrew from the race in 1987 amid accusations that he had plagiarized passages in his speeches.

Mr. Biden has about $3 million in his Senate campaign account that will transfer to his presidential committee, Rasky said.

The campaign will be run by Luis Navarro, a longtime Democratic activist with close ties to organized labor. Recently, Navarro headed the Florida Democratic Party and served a stint as political director for Massachusetts Sen. John Kerry’s 2004 presidential bid.
