WASHINGTON (AP) - President Barack Obama says the Supreme Court's decision to uphold his health care overhaul is a "victory for people all over the country" and will make their lives more secure.

Obama says the decision upholds the fundamental principle that in America - the wealthiest nation on earth - no one should fall into financial ruin because of an illness.

The president says the decision means that people with pre-existing medical conditions will not be discriminated against and people will be able to afford quality health care.

The nation's highest court on Thursday upheld the individual insurance requirement at the center of the president's overhaul.

Polling has suggested that most Americans oppose the law and Republican presidential candidate Mitt Romney vowed again after the ruling to seek its repeal.

Republican Mitt Romney is promising that he will repeal the federal health care law the Supreme Court just upheld.

He called the decision incorrect and said Thursday that it is "bad law." He says it raises taxes and cuts Medicare.

Romney says that, if elected in November, he will work to repeal and replace the law. But he hasn't said precisely how.

As Massachusetts governor, Romney signed into law a measure that required all state residents to have health coverage. That notion was the cornerstone of the law enacted by President Barack Obama and congressional Democrats. The high court decided it was constitutional.
