President Barack Obama said on Tuesday he was not spending "a whole bunch of time" preparing contingency plans should the Supreme Court overturn his healthcare overhaul law because he is confident the justices will uphold it. It was the second straight day that Obama has applied pressure in court of public opinion as the nine justices deliberate the fate of the Affordable Care Act. Obama also weighed in with a legal argument, saying the high court was unlikely to strike down a law passed by Congress "on an economic issue like healthcare that I think most people would clearly consider commerce."
