Bruh, you are one of those "I heard you" types? You hear people but don't listen? I don't support "Do nothing." I said what they should do, but what they can do legislatively to stop what is coming? Nothing. The old term "Trying to make a dollar out of 15 cents" comes to mind. They CAN'T do anything outside of running their mouths and saying no. Its literally what Republicans did to Obama when they couldn't stop anything until they won in the midterms his first go. Only difference is Obama wasn't trying to topple democracy so it's easy to forget.
The voting public voted or didn't vote for various reasons and it wasn't messaging. They either felt economic anxiety, were never going to vote in a woman (hence Latino vote going Republican for one), or were simply on the white supremacist wave. You do know the majority of voters are white, right? They went Republican. Add in the peeloffs from Latinos and a few other groups and we got what we got.
As for the algorithm, it is not a reason FOR them losing, but it explains stupid shyt like people googling if they can change their vote and if biden dropped out. Most people are not really paying attention to politics. They make their November decision in October. "Messaging" doesn't work if people literally don't see it. The Joe Rogan trump interview is currently at 5 million views on youtube. Kamala with Oprah is at 2.6 million. Not only did they not go to the right people but the "right people" also had an audience that wouldn't have been receptive to her. That is a problem with Democrats not having the media apparatus to back them like Republicans do, and that extends to popular influencers and podcasters. That said, the algorithms are a thing.
Lastly, you did not say what they should be doing. If nothing else, ignore everything else I said. Did you vote Democratic? If so, there was no further message for you. For those they don't have in the bag right now, what should they be doing? Getting arrested? Taking protests to peoples businesses? What should they be doing? PLEASE answer that question with an answer, not a "Don't do this" answer.
