President Obama used his State of the Union address Tuesday to pitch a host of new ideas for government "investment," while at the same time calling for a renewed effort to shrink the deficit.

After an election dominated by concerns over federal spending, some lawmakers questioned whether the president was offering enough serious ideas for tackling the national debt.

The following is an overview of the president's State of the Union ledger, showing the proposed revenue/cost-saving measures and proposed expenses laid out in the speech Tuesday night.

Revenue/Savings

-- A five-year freeze in domestic spending, projected to save $400 billion over the next decade.

-- Elimination of billions in tax breaks for oil companies. The president has previously sought to bring in more than $36 billion over the next decade through tax increases on oil and gas companies, but so far has been unable to win congressional support.

-- Reductions in health care costs, including Medicare and Medicaid. Obama said he's willing to consider medical malpractice reform to "rein in frivolous lawsuits" and presumably drive down health care costs to the government in return. Though that proposal so far has not moved far beyond talking points, the Congressional Budget Office and Joint Committee on Taxation in 2009 estimated that tort reform could reduce federal government health care costs by $41 billion over 10 years.

-- Reform for Social Security. Obama did not offer specifics.

-- Ending the Bush-era tax cuts for the wealthiest 2 percent of Americans once the latest extension expires in two years. Before the rate was extended, the Obama administration estimated it would cost $700 billion over the next decade.

-- A proposal to "merge, consolidate and reorganize the federal government." Obama said he'll submit that proposal to Congress "in the coming months."

-- A ban on congressional earmarks.

-- A proposal to lower the corporate tax rate. Obama pitched this as part of a broader effort to simplify the tax code -- he pledged the changes would not add to the deficit.

Expenses

-- Pledge to provide 80 percent of Americans with high-speed rail access in 25 years.

-- Pledge to have 1 million electric vehicles on the road by 2015.

-- Pledge to have 80 percent of the country's electricity come from clean-energy sources by 2035.

-- New investment in biomedical research, information technology and clean-energy technology.

-- A continuation of the $4.35 billion Race to the Top incentive program offering competitive federal grants to local school systems.

-- A call to "redouble" efforts to repair America's aging roads and bridges.

-- A call to make a $10,000 tuition tax credit permanent.
