FILE -In this March 23, 2010, file photo President Barack Obama is applauded after signing the Affordable Care Act into law in the East Room of the White House in Washington. If the law survives Supreme Court scrutiny, it will be nearly a decade before all its major pieces are in place, and even if he is re-elected, Obama won't be in office to oversee completion of his biggest domestic policy accomplishment, assuming Republicans don't succeed in repealing it. The law's carefully orchestrated phase-in is evidence of what's at stake in the Supreme Court deliberations that start March 26, 2012. (AP Photo/Charles Dharapak, File)
