OKLAHOMA CITY (AP) - Looming decisions for Gov. Mary Fallin on how Oklahoma will respond to the federal health care law are prompting an energetic, behind-the-scenes lobbying effort by hospitals, insurance companies, and other constituencies that will be affected.

Fallin is expected to announce within the next week her position on whether the state will move ahead with setting up a state-based online health insurance marketplace required under the sweeping law. Oklahoma policymakers also must decide whether the state will expand its Medicaid eligibility to provide coverage to thousands of low-income, uninsured citizens.

Fallin has yet to stake out a position on either proposal and faces a delicate political balancing act in a state where Republicans have bitterly resisted the requirements of the federal health care law.
