President Barack Obama's health care overhaul has divided the nation, and Republicans believe their call for repeal will help them win elections in November. But the picture's not that clear cut. A new AP poll finds that Americans who think the law should have done more outnumber those who think the government should stay out of health care by 2-to-1. "I was disappointed that it didn't provide universal coverage," said Bronwyn Bleakley, 35, a biology professor from Easton, Mass. More than 30 million people would gain coverage in 2019 when the law is fully phased in, but another 20 million or so would remain uninsured. Bleakley, who was uninsured early in her career, views the overhaul as a work in progress.
