WASHINGTON (AP) — America's national shouting match over health care will only get louder next week as the Supreme Court weighs the fate of President Barack Obama's overhaul.

With formal arguments off-limits to cameras, supporters and detractors have laid elaborate plans to compete for the public's attention outside the Supreme Court building.

At the White House, which on Friday observed a low-key second anniversary of the Affordable Care Act, Obama's advisers are trying to walk a fine line. They want to avoid any appearance of unseemly pressure on the justices while encouraging supporters to speak up. The Obama re-election campaign is also talking up the law's benefits, and there is a steady stream of cheery press releases from the Department of Health and Human Services.
