Pessimism of the mind. Optimism of the spirit. You are correct that there are a lot of ways things can go wrong, but that just means we need to put in the work to overcome those obstacles. Put that pessimism to work by using it to predict and surmout roadblocks. If you feel phone calls arent enough, go door knock. If you feels door knocking isn't enough, start organizing. If you feel organizing isn't enough, run for office. Get more and more involved in politics until you understand in your soul that a better future is possible, if only we all work together to make it happen.

You're being a bitter crumudgen because there are now more Democrats that fought and won against AIPAC money and big money politics with good policy platforms. They ran on a platform of Medicare for all, ending wars, and more progressive policies. We need to see how it shakes out, and calling them ShitLibs is just naked cynicism. When it inevitably comes down to corporate Democrats blocking these efforts, you can go ahead and call them out, but the only way forward is to primary them with better people. Pretending like the new batch is the old batch is disingenuous.
