ABA Journal: The U.S. Supreme Court hasn’t agreed to review the Obama administration’s health care law, but that hasn’t stopped the pundits from making some predictions.

The swing voters may be Chief Justice John G. Roberts Jr. and Justice Anthony M. Kennedy, Reuters reports. At issue is whether Congress had the constitutional authority to include a provision requiring Americans to buy insurance or to pay a penalty.

The court’s four liberal justices are likely to vote to uphold the law, constitutional experts told Reuters. But they disagree on likely votes by some of the others.
