Washington ? Democrats are attacking President Bush’s budget for worsening the already bleak deficit picture, even as a new congressional analysis of his fiscal plans shows no end in sight for huge amounts of red ink.

A report Friday by the nonpartisan Congressional Budget Office said under Bush’s budget, federal deficits over the next 10 years would get no lower than a projected $229 billion in 2010. It excluded the potential costs of Bush’s plan to revamp Social Security, any costs for wars in Iraq and Afghanistan after this year, and other possible expenses.

The CBO also raised new questions about the president’s ability to meet his goal of halving federal deficits by 2009.

The report projected a deficit that year of $246 billion. That would meet Bush’s target of halving the $521 billion shortfall he projected for last year — a figure that ended up being $109 billion too high. But it would not be close to cutting last year’s actual, record $412 billion deficit in half.

“The president talks about not wanting to pass burdens to future generations,” Sen. Kent Conrad of North Dakota, senior Democrat on the Senate Budget Committee, said in his party’s radio address Saturday. “But his budget does precisely that — passing on a crippling and growing debt to our children and grandchildren.”

Conrad said Bush’s plan for creating private savings account as part of Social Security will only “dig the hole deeper” because he would borrow money to set them up.

“We’ve got to save and invest now to strengthen the economy for the future, keep Social Security and Medicare solvent, and prevent more difficult choices down the road,” Conrad said.

Rep. John Spratt of South Carolina, top Democrat on the House Budget Committee, said the report’s “deficits paint a dismal picture, which the president’s budget only makes worse.”

The new figures were released days before the House and Senate Budget committees plan to write their own spending plans for the coming year.

The panels’ chairmen, Rep. Jim Nussle, R-Iowa, and Sen. Judd Gregg, R-N.H., have been hunting for GOP support for packages following Bush’s proposals to restrain spending and halve deficits.

Friday’s figures helped highlight the longer-term budget problems that lie ahead as the baby boom generation starts retiring this decade and drawing on already costly programs like Social Security and Medicare.

The CBO report said Bush’s budget would yield deficits totaling $2.58 trillion during the 10-year period ending in 2015. That is $1.6 trillion higher than they would be if none of the president’s fiscal plans become law, it said, the chief factor being his intention to make already enacted tax cuts permanent.
