The kind of thing that allowed Biden to get so far into the re-election cycle, etc. My favorite recent example is one ive heard from numerous people in real life, is suggesting that the main reason Kamala lost was because she was a woman. Or confusion at all the Texas border counties flipping to Trump. Dems dropped the ball in so many obvious ways and its deeply frustrating that its still difficult to have serious conversations about it. The reality is many of my left leaning friends are still deep in echo chambers they can barely see; its quite different from my right leaning friends who feel a bit closer to delusional on a few particular issues (ie consistently discard and avoid incorporating relatively mundane facts such as low murder rates vs "this is the most dangerous time ever for a child to be outside").
