Campaigns both claim advantage on Medicare battle

The political battle over Medicare, brewing since Mitt Romney named Paul Ryan as his running mate, showed no signs of easing Sunday, with operatives from each campaign claiming their side had an advantage with senior citizens concerned about their government-funded health benefits.

Romney senior adviser Eric Fehrnstrom, speaking on CNN's "State of the Union," said his campaign wasn't worried that seniors would be turned off by Ryan's House budget plan, which proposes allowing private insurers to compete with traditional Medicare on an exchange.
