"Less than a year before Americans will be required to have insurance under President Obama's healthcare law, many of its backers are growing increasingly anxious that premiums could jump, driven up by the legislation itself."

"Tens of thousands of Americans who cannot get health insurance because of preexisting medical problems will be blocked from a program designed to help them because funding is running low.

Scott Walker announced Wednesday that he won't propose expanding Medicaid services in Wisconsin, joining other Republican governors who have decided to reject federal money for covering more low-income residents under the health care overhaul law. Instead, Walker outlined a hybrid approach that would allow more adults into the state health program, which he said would help cut the state's uninsured rate of 14 percent in half."
