The US Supreme Court Tuesday took up the most contentious part of President Barack Obama's landmark health care reform, hearing arguments on whether it is constitutional to require Americans to buy insurance coverage. The second day of an unprecedented three days of arguments into the Affordable Care Act, derided by opponents as 'Obamacare' but hailed by supporters as a major achievement, has focused national attention on what could be a decisive issue in the 2012 presidential elections.
