Its easy to inform the present with the recent past though. I think Biden and Clinton are part of the same system that wants the Democrats to stay the same center-right party they have been since the 90s. To me, Clinton's failure is a failure of the ideology she represented, third-way neoliberal economics, if Biden is chosen, I think he will repeat some (but not all) of the mistakes Clinton made. When Trump attacked Hilliary as a neoliberal and a war hawk, she had no answer to this and ceded a lot of ground Trump and I think Biden will do the same.
