A new bipartisan effort to cancel the Affordable Care Act's Cadillac tax -- the 40 percent levy on high-cost health insurance plans -- adds a wrinkle to an impending fight in Congress. The repeal bill unveiled Thursday in the Senate by Nevada Republican Dean Heller and New Mexico Democrat Martin Heinrich stands little chance of becoming law soon, especially with Barack Obama in the White House. Yet it demonstrates lawmakers' frustration with the tax, which takes effect in 2018. (Rubin, 9/17)

Forget "repeal and replace." An obscure Obamacare provision that takes effect in 2017 could empower a Republican president to unravel Obamacare — without a single vote from Congress. The provision allows the executive branch to waive big chunks of the law for a state that chooses a different approach to expanding health coverage. It was designed to allow progressive states to go further than Obamacare. Vermont, for instance, wanted to create a single-payer plan. (Pradhan, 9/17)
