The alternative is to pressure the democrats into doing the things they need to do to win the election. Currently they are laboring under the delusion that they can win just by saying “Oh, we want the things you want, we’re just powerless until you give us uhhh 50% in the senate! No 61! No, 64 because of Fetterman, Sinoma, and Manchin! You can do it, just vote a little harder and we’ll stop doing the opposite of what you elected us to do!” and “Well trump would also do the horrible things we’re doing, so you have to vote for us”.
That’s why they lost in 2016 and 2022, and trying to silence criticism just helps them maintain that delusion.
