Democrats say he has no plan because at a fundamental level, leadership supports most of the policies that Trump pursues.
Its not a question of the relevancy of Democrats or Trump's ego: Its that both parties accept and operate to support the same corporate, zionist, fascist donor base.
Its why you weren't permitted an anti-genocide candidate in 2024: Because it wasn't in the donor classes interests. Its why they convinced Democrats to hold onto Biden as a candidate long as they did. Its party of why Harris was effectively "selected" as the nominee instead of running a real primary (for example, as Jon Stewart had suggested). Its why Harris ran on a campaign of "Nothing would fundamentally change", while as an administration, having sold out both progressives and the BLM movement as a voting block in the period of 2021-2024. Democratic voters have been voting against their own interests, just like Republican voters, for decades.
There is no future or path to a better future through the traditional pathways to power in the Democratic party as it currently exists. Its structurally not possible. And this inability to adjust to an electorate with significantly different priorities than those who control power within the party is a constant headwind: By constantly being on the wrong sides of issues, like they are today, Democrats damage their ability to win elections.
For leadership, this isn't a problem: They still get the policies they desire. For the electorate, or people running for office who want to change the Democratic party to one people actually want to vote for, this is a huge problem.
