LOS ANGELES (AP) - California will test President Barack Obama's health care overhaul like no other state.
On Tuesday the law's new marketplaces will open for business, allowing consumers to comparison shop between insurance plans online.
California is home to 15 percent of the nation's uninsured, or roughly 7 million people - a number that exceeds the population of Arizona.
The state will be closely watched as a barometer for the Affordable Care Act, better known as "Obamacare."
It's the most extensive change to the nation's health care system since Medicare became law in 1965. Yet surveys show many Californians remain perplexed by the law and what it means for health care services.
Beginning in 2014, virtually all Americans will be required to have health insurance or pay an annual penalty to the government.
