If you consider the bigger picture it's not silly at all.

Democrats spent four years, two of them with the same amount of power that Donald Trump has, letting people get significantly poorer and aiding a genocide. Then, they fronted an openly demented candidate who had a meltdown on national TV. Then, they let the brain-dead candidate crown a candidate who couldn't even beat Tulsi Gabbard in a primary. After that, they spent three months of campaign time offering no policy changes, but just telling people to 'be joyful'. Then, after that, Harris publicly affirmed she wouldn't do anything differently than Biden had.

TLDR: Democrats made voters hate them just that much. You can't tell tens of millions of people working 100 hours a week at three jobs just to afford a roach-infested studio that you're not going to make their lives better. Sure, Dems say they support better things, but no one believes them anymore.
