Washington, D.C. ? Republican presidential candidate Sam Brownback said Social Security can be fixed with private savings accounts, a case President Bush has made without success during his second term in office.

Workers would invest a little less than half of their payroll taxes in stocks and other market-based investment funds under a plan the Kansas senator will lay out in a speech today to the anti-tax Club for Growth in Palm Beach, Fla.

Brownback is well-liked among conservatives because of his firm stances on social issues, such as his resistance to gay marriage, embryonic stem cell research and abortion. But he wants to be thought of as a fiscal conservative, too.

Under his plan, people could choose to remain in the old system, but young people would automatically get private retirement accounts as they enter the work force.
