Jonathan Cohn, WNYC: The immediate cause was an enactment of the Inflation Reduction Act, that big law that Biden and the Democrats passed last year. It's probably best known for its climate provisions. This is the law that puts all this money into clean energy and electric cars. There's a whole section of the law that deals with healthcare, and the biggest part of it deals with prescription drug prices in Medicare, which as you said, is something Democrats have been working on trying to do something literally for decades. This is one of their longest-standing crusades. A year ago, they finally with the leadership in Congress with President Biden, they finally got something over the finish line.
