The Democrats problem is tha they won’t do any of that because their donors dont want it. But as long as the DNC values their donorsore than their voters, they will continue to lose elections.
The entire American political system we have is dependent on big money donors since citizens united. America has been an oligarchy since at least the early 2000s. You will not get a Democratic party with policies that vary wildly from what industrial heads and CEOs want simply by voting (or not) every 2-4 years. And even small deviations from what they want aren’t tolerated by many of the oligarchs (e.g. Elon Musk).
