What would be the reasonable thing for the democrats to do right now? They weren’t allowed to see the tax bill. That’s what happens when something has the 51 republicans and it can’t be filibustered in the current environment.
Further, the republicans haven’t even brought a bill forward to be filibustered likely because they don’t have the votes in their own party.
I’m fairly centrist for this site but the republicans controlling every part of the government as well as already using their reconciliation power and blaming the democrats is so shockingly perverse in its cinycism. That’s before you even take into account the duplicity on DACA that has broad bipartisan support up to a meeting with the president last week.
Neither morally or strategically should the democrats budge on this.
