The Democratic Party loves nothing more than doing nothing and losing elections. Doing things risks upsetting donors. When you don't have power, it's easy to promise progressive policies that you have zero chance of enacting (eg Kamala Harrais was for Medicare-for-all in 2019 [1]). They are the controlled opposition party [2].
Trump advertized everything he was going to do and is now doing [3], despite briefly distance himself from it [4] when it became unpopular for the brief period Democrats messaged about it. Nobody actually believed that. The majority of the authors are former Trump staffers. No one in politics can feign shock or surprise.
We know Democrats are capable of fighting. The problem is they only do that against progressive elemnts of their own party. It's not just Bernie Sanders either (both times). Look at the history of Buffalo mayor Byron Brown [5].
Progressive policies are incredibly popular. Democrats are not. In places like Florida, Kansas and Missouri, ballot initiatives outperformed Harris-Walz by as much as 20 points.
Democrats won't even lie to us about enacting progresive policies. The Democratic leadership and donors are more comfortable with Trump being in power than Bernie Sanders. They're also more interested in protecting the Israeli settler colonial project than winning elections.
Not every Trump voter is a Brownshirt either. Many are simply working people who have legitimate grievances, abandoned by the Democratic economic policies that favor corporations over the New Deal that allowed Democrats to control Congress for almost 60 years.
Whatever bad stuff is going on now, Chuck Schumer and Hakeem Jeffries are absolutely complicit in it.
