If you're serious, than you (Dems and American Left in general) are condemned to repeat the mistake that already have brought you spectacular defeat twice.

Biden's victory was a diversion from the rising trend, and not Trump's before him. So, indeed, Harris shouldn't be blamed too much for her word salad; her candidacy and attempts to paint her as an agent of changes are but two indicators of deep internal crisis inside the Dem Party, which stemmed from internal polarization steadily gaining force in the Gilded Age of Information.

After eviction of all independent persons capable of pragmatic thinking outside the box of agenda, e.g., RFK Jr or Tulsi Gabbard, Dems found themselves in a dusty, gloomy attic where only meek, vacuous, inane candidates were still dwelling.

Disclaimer incoming: I’m not an American citizen and as such ain’t eligible to vote, but in case I’d be able to, I’d have chosen the third option decisively, i.e., RFK Jr & Nicole, if only they had not quit the race. Otherwise, I would abstain or support Stein, because of her anti-warmongering stance.
