Any unbiased “what if candidates had done things differently” evaluation must include the actions of all candidates that resulted in a Democrat loss. This means it should include how much Clinton herself screw her own chances, for example by comparing the votes she got on those states with the votes previous Democrat candidates got in those states.

(I strongly suspect that Clinton has a far larger proportion of the blame for her own defeat than all 3rd party candidates put together)

This focus on blaming everybody else but your own leaders is just the traditional tribalist mindset of “the chief is good, it’s everybody else whose a problem”. The decades long enshittification of the Democrat Party is mainly the product of its supporters acting as mindless tribalists rather the rationally, thus not holding their “chiefs” to same standards as they do everybody else.

Unsurprisingly we see the very same problem of the Democrat Leadership having carte blanche from the party fans to do just about everything and even damage their own electoral chances - with, as we see right here, the members of the tribe eagerly scapegoating it all as being the fault of 3rd party candidates - with their support for the Israeli Genocide.
