People attribute a lot more competence to the DNC then they've really demonstrated.
Like yeah HRC might have legitimately thought that way about Trump, but if her own campaigning didn't win the election for herself suggesting it's what put Trump over the finish line or even that it was of any significant contribution is pretty disingenuous.
Not to mention how the DNC and HRC aren't able to mind control voters, like 99% of attempts to make Trump into the DNC boogeyman's fault ignore the choice voters made to vote for him or to just not vote for Clinton, and the "shoved Clinton down our throats" narrative is pretty racist since it basically casts Clinton's primary win through significant support by the black and poc vote as illegitimate.
We almost had a double down on that shit in 2020 but the "low information voter" dog whistlers just decided to blame everything on Clyburn this time.
