Romney and Obama preview reactions to healthcare ruling

In dueling Southern campaign stops Tuesday, President Obama and Mitt Romney previewed their likely responses to the Supreme Court's highly anticipated healthcare ruling, with the Democratic incumbent warning against refighting the reform battle and the Republican deeming the question one of states' rights and personal responsibility. Romney has defended the plan he imposed in Massachusetts —which, like Obama's, increased the number of insured citizens—but has said that he would let individual states, not the federal government, set healthcare coverage for their residents. Obama, speaking simultaneously at a downtown Atlanta hotel, sidestepped what the justices might decide and instead underscored the consequences if Republicans followed through on a pledge to repeal the law.
