This afternoon, the House is set to vote on a bill to limit medical malpractice lawsuits. House Republicans, including Speaker Paul Ryan, are advertising it as a way to reduce the cost of health care, and the idea has been a mainstay of GOP health-care proposals for years. But it's also a topic that divides conservatives — because some say it's not a good idea to let the federal government override states' laws on issues like limiting non-economic damages.
Key quote: Here's what Ed Meese, former attorney general under President Ronald Reagan, wrote in a letter to Ryan: "It will never be acceptable to substitute unconstitutional Democratic-sponsored legislative mandates with Republican ones."
Why it matters: Even if the medical malpractice legislation passes the House, it's highly unlikely to go anywhere in the Senate — not just because Democrats would oppose it, but because some Republicans would, too.
