I get this argument, I really do, I feel it, but it feels incomplete without admitting that needing Harris to lose requires Trump to win. Just ignoring the orange elephant in the room in all these discussions (valid discussions!) about punishing the Dems feels a little disingenuous to me.
It seems to me Harris needs to lose, as signaling via her election that the heinous actions of the Biden-Harris administration are fine would be further disaster.
