Obama Shifts Campaign to Medicare
President Barack Obama used his regular weekly radio address Saturday to continue pounding away at Republican plans to overhaul Medicare. The address underscored the new prominence Medicare has assumed as a campaign issue in the past two weeks. Paul Ryan, Republican, Mitt Romney's runnign mate, has championed an alternative to the government-run Medicare program that would provide vouchers to older Americans for the purchase of private health insurance. "I'm willing to work with anyone to keep improving the current system, but I refuse to do anything that undermines the basic idea of Medicare as a guarantee for seniors who get sick," Obama said.
