[Assuming] a wildly optimistic scenario in which Dems do about as well as they can be reasonably hope to do in the 2020 Senate elections and a majority decides to eliminate the filibuster, passing any legislation will require at least two Democratic senators who are refusing to even commit to endorsing the Democratic nominee in 2020. Medicare For All is not going to be passed in the next Congress. Joe Biden’s robust public option, for that matter, is not going to be passed by the next Congress. This is true no matter who becomes president. This is about establishing long-term goals and mobilizing voters — that’s it. So Warren’s plan is fine, Bernie’s plan is fine, and to act as if difference in minor details in them will have policy consequences for the next administration or should influence anybody’s primary vote either way is nuts.
