You could be right, though I do think that we can't say for sure until they (i.e. non-corporatists) actually get a shot. What we can say is that the US is in this mess after nominating corporate dems for decades and asking for people to vote for the "least bad" option. Watching interviews with working class who voted Obama and now Trump shows that this is a core reason. Yet online there's still a huge number of people advocating for repeating the same thing expecting different results.
I think one reason why this is especially bad in the US is because of its cultural optimism, which inherently leads to extreme shorttermism. People are vouching to support Clinton/Biden/Harris/... because of blind optimism that somehow after 4 years thing will get better, to an extent of willingly completely ignoring the previous decades and somewhere deep down knowing that doing it is probably worse in the long term.
