Yes, yes, we do seem to be stuck on this whole shared chorus that progressives all keep repeating in unison: "My repetition of MAGA talking points where I tried to convince anyone who would listen that Dems are bad can in no way have had any effect, nor can the other couple of thousand of my compatriots saying the same thing."
Unfortunately, what "people are saying" really does have an effect. There is a reason bots are all over social media sharing ridiculously far right or far left ideas. They want people to think those ideas have traction, and take them and run with them. You are pouring your little cup of gasoline onto the fire and then claiming it doesn't matter because you are just one person with a cup. If enough people believe they have no effect, the fire never goes out.
Oh, ok, I "agreed" that there were flaws in the Dem strategy, and posted them myself several times. That surely is materially different.
I am genuinely baffled by this. You are asking me to imagine a Democratic politician acting like a random person on the internet who has spent a decade posting far right content? I don't follow the point you are trying to make at all.
