Walker opposes the Affordable Care Act, saying it requires “the majority of people in Wisconsin to pay more money for less health care.” He opted against having the state set up the law’s health insurance exchange, deferring to the federal government to run it. Wisconsin joined other states in a mostly unsuccessful lawsuit challenging the law.

Burke said she supports the law’s goals and many of its provisions, such as banning denials of coverage for people with medical conditions and ending caps on benefits.

But she is “concerned,” she said, “that we haven’t yet seen the cost savings we need.”

The Medicaid debate

The part of the law that comes most within a governor’s purview is the Medicaid expansion.

The law allows states to get federal funding to fully cover people with incomes up to 133 percent of the poverty level, or $26,321 for a family of three, through 2016. Later, the federal government will cover at least 90 percent of the costs, up from its usual share of 60 percent.
