Well first we need an overwhelming blue wave so the GOP in its current form collapses. Then, as they shift back towards the center, the more progressive part of the Democrats have a better shot at winning. With these razor sharp margins, it will be a race to the center for Democrats as the GOP goes all in with crazy.
You’re either arguing in bad faith, or have no idea how the government works. I said the democrats need a blue wave since they haven’t controlled the presidency, and both houses of Congress for more than a couple months over the past decade. What did you expect Biden to do when you have a Republican controlled House and such a thin margin in the Senate?
