House Minority Leader Nancy Pelosi attacked the Paul Ryan plan to turn Medicare into a voucher program at a breakfast in Charlotte, North Carolina, ahead of the Democratic convention, CNN reports. Pelosi called the plan a "trick to end Medicare."
"It's wrong. It's morally wrong. It's economically wrong," Pelosi said. "To vote for Medicare, vote Democratic."
Biden also went on offense on the Medicare Monday with a slightly different slogan: "We're for Medicare, they're for vouchercare."
The Romney campaign began going on offense over Medicare when Romney brought Ryan onto the ticket, claiming that Obama had raided Medicare and that he would save it.
