Pelosi expects court to vote 6-3 in favor of Obama health care law WASHINGTON -- As Washington awaits the Supreme Court's ruling on President Obama's healthcare law, Rep. Nancy Pelosi (D-San Francisco) said the Affordable Care Act would withstand the constitutional challenge before the court and be upheld. "I know the Constitution - this bill is ironclad," Pelosi, the House minority leader, said Thursday. It is ironclad. The nation's new healthcare law, a signature legislative achievement of Obama's tenure in office, was signed into law in 2010 but was immediately challenged by attorney generals from more than two dozen primarily Republican-led states. Joined by small businesses, they questioned the constitutionality of one of the law's central provisions: that all Americans must have health insurance by 2014. Few political leaders in Washington have been willing to publicly wager on the outcome as the court considers the case, but Pelosi reiterated her belief that she expected the justices would rule 6 to 3 to uphold it. "Nobody was frivolous with the Constitution and the health of the American people in writing the bill," she said. That's where my confidence springs from: the merit of the bill and the nature of the Constitution. The makeup of the court -- well, we'll see. The court is expected to deliver its opinion by late June, as Republicans in Congress continue efforts to dismantle pieces of the law that is a key element of their election-year attacks on Obama and his Democratic allies in Congress. Mitt Romney, who is positioned to be Obama's Republican challenger, has said he would seek to repeal the law.
