Washington (CNN) -- In a landmark ruling that will impact the November election and the lives of every American, the U.S. Supreme Court on Thursday upheld the controversial health care law championed by President Barack Obama.
The narrow 5-4 ruling was a victory for Obama but also will serve as a rallying issue for Republicans calling for repeal of the Affordable Care Act passed by Democrats in 2010.
An administration official described the White House reaction as elation, while GOP opponents criticized the high court's reasoning and promised an immediate repeal effort.
"Today's decision was a victory for people all over this country whose lives are more secure because of this law," Obama said in a televised White House statement.
Certain Republican presidential nominee Mitt Romney's campaign reported a fund-raising spike of $300,000 just after the high court's decision was announced, and Romney said defeating Obama in November is the only way to get rid of the law despised by conservatives as a costly expansion of government.
Thursday's decision impacts how Americans get medicine and health care, and also provides new court guidelines on federal power.
