If you passed it in the first place, and counted on repealing it before it would have taken effect, and failed to do so, then I blame you for passing it in the first place.
They had the chance to repeal it before it would have taken effect.
Why do they get zero blame on here?
But the Republicans made this change to start with. That's a lot of blame. And if they did it just to create a political firestorm against Democrats later (which is exactly what they did), do we (A) recognize that politicians shouldn't be using Americans as cannon fodder to damage their political enemies or (B) blame their political enemies?
It gives advantage to bad actors.
Both sides are the same, Republicans destroy things and Democrats are not perfect in stopping and fixing them! "I am gonna support Republicans as they create problems and then blame Democrats" just makes you someone who intentionally creates problems.
