Caren,
A chunk of their "do-nothing" is that they are out of power. And, an act-up in the chamber could look stupid.
They have yet to reckon with the 2024 loss. The meeting where they elected a new party leader failed to achieve this.
Mapping the American future is a place to start. They need to break with the past (forget minimum wage, unions, and appealing directly to the working class) and, above all, think BIG and FORWARD.
Democrats can prepare Americans for the AI world, which will be as disruptive as globalization. They can embrace AI while tending to its downsides, which was a fundamental mistake with globalization.
Focusing on the engines of prosperity and security (innovation, immigration, and trade) in a new marriage of capitalism and socialism (find new names if necessary).
Best.
