Vice President Joe BidenJoe BidenBiden: I regret not being president Biden: 'McCain is right: Need select committee' for Russia With no emerging leaders, no clear message, Democrats flounder MORE on Saturday mocked Republicans for acting like they invented Medicare.
"If you came from another country and you just listened to their convention, you'd say, those guys came up with a great idea 50 years ago," Biden said at a campaign rally in New Hampshire. "You'd think it was a Republican idea."
Republicans have been touting their plan to partially privatize Medicare, a plan that would allow senior citizens to choose between the program or a subsidy to help pay for private insurance.

But they have been faced with obstacles on selling their plan. On Friday, Rep. Paul Ryan, the GOP vice presidential nominee, drew boos when he attacked Obama's healthcare law, saying it had weakened Medicare. It was a sign of the challenge that lies ahead for Republicans on the issue.
At the campaign rally on Saturday, Biden sought to explain that the program has improved under the Obama administration and that "under the president's leadership, we in fact increased benefits," he said. "Anybody on Medicare today... ask them. They have more benefits today than they did the week we came into office."
