After winning re-election in 2004, Bush made the partial privatization of Social Security his top domestic priority. He proposed restructuring the program so that citizens could invest some of the money they paid in payroll taxes, which fund the Social Security program. The president argued that Social Security faced an imminent funding crisis and that reform was necessary to ensure its continuing solvency. Bush expected a difficult congressional battle over his proposal, but, as he put it, "I've got political capital, and I intend to spend it." Groups like the AARP strongly opposed the plan, as did moderate Democrats like Max Baucus, who had supported the Bush tax cuts. Ultimately, Bush failed to win the backing of a single congressional Democrat for his plan, and even moderate Republicans like Olympia Snowe and Lincoln Chafee refused to back privatization. In the face of unified opposition, Republicans abandoned Bush's Social Security proposal in mid-2005.
