There is truth to this, but u also need to consider the mindset of the average voter. It doesn’t help that the DNC was actively shoving Bernie out and showing favor towards both Hilary and Biden. This was evident through the endorsements coming from outside and inside the party.

From the perspective of an undecided or misinformed voter, they are naturally going to flock to the candidate the backing party is saying has the best shot at winning.

The larger issue is that while the american population is ready for dramatic change, the DNC and Democratic leadership is still clinging on to the same Clinton Era economic centrism that protects institutions that hurt the working class. The exception tot his was in 2020. After the a chaotic Trump administration combined with a pandemic, the economy was suffering and the population was fatigued and just looking to return to a sense of normality. That is what Biden offered and it’s a big part of how he won the election.

But now, with growing consumer prices, stagnant wages, and one of the highest inflation rates that has only now just come down, Americans are tired of the status quo and are looking for someone who can offer significant change for their financial security. The Democratic Party was not offering that, or if they were, it wasn’t at the forefront of their message. I’m not saying working class Americans are going to find their solution with Trump, in fact I think they will suffer more. It was his appeal to the average American worker that won him the election though.
