There is no progressive future without fixing the damage on the Supreme Court. In 2018 it is critical Democrats get majorities in the Senate (except Manchin, he can eat a ****). But in 2020, it is critical that we hold Democrats to a Court Packing litmus test.
IMPORTANT: This isn't a litmus test that says "I'm not gonna vote for Dems if they don't do what I like." This is a litmus test that says, "I'm going to check with the politicians from my district and state and if they aren't going to pack the courts, then I will run against them."
You don't have to vote for the lesser evil if you run to be the greater good.
