This week's 4 political ads that stretch the truth

The ad: "Paid in," by Mitt Romney for President

The key quote: "The money you paid for your guaranteed healthcare is going to a massive new government program that's not for you."

The Problem: This Romney ad suggests that the money seniors have paid for Medicare benefits would pay for the Obama administration's health care overhaul at the expense of their benefits. As CBS News pointed out earlier this week, the president's health care reform law is paid for in part by reductions to Medicare. According to data from the Kaiser Foundation, however, the reductions come primarily from cuts to Medicare Advantage plans, as well as in hospital reimbursements and in payments to other providers, and would not limit access to benefits for Medicare recipients. Republicans argue such reductions create disincentives for hospitals and doctors to accept new Medicare patients, but it's a stretch to say that the Affordable Care Act is "not for you" when Medicare recipients have access to equal benefits under that plan.
