Mitt Romney disclosed on Sunday that he would keep several important parts of Barack Obama's overhaul of the American health care system, altering earlier vows for a blanket repeal of the president's most significant legislative achievement. Romney suggest he would keep provision related to pre-existing conditions and young people. "I say we're going to replace Obamacare. And I'm replacing it with my own plan," Romney said. "And even in Massachusetts when I was governor, our plan there deals with pre-existing conditions and with young people."
