If all that happens is stomping, you are right. We need to punish the R's who made this happen and take our party back. The only way they do not repeat this behavior over and over is if there are no consequences.
No, we don't need to "punish" the R's. That's nothing more than "stomping", and it helps nobody but the Democrats who'll replace them in the legislature.
The intelligent thing to do is to recognize that there are actual merits to both C and D, in that they address some actual problems with TABOR.
Rather than "punishing" your allies, and stomping off in a rage as you're planning to do, perhaps your energy would be better spent finding ways to improve TABOR, so that things like Ref. C can't get proposed in the first place.
