With the future of Medicare on the line in the presidential election, The Associated Press asked the Obama campaign five questions about how his plans for seniors' healthcare would affect critical issues of costs and benefits. Unlike Romney, Obama is not calling for a major Medicare remake. Most of the president’s cost-cutting ideas are incorporated in his healthcare law, and will phase in unless Romney wins and makes good on his pledge to repeal it. Other Obama proposals are drawn from government advisory groups or bipartisan commissions seeking consensus on how to reduce deficits. AARP gave a thumbs-down to this year’s Obama budget, citing Medicare cost shifts.
