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.
At this point, I disagree. We need some peasants with pitchforks to get the attention of the folks who run this party. If they do not think there are consequences for what they have done to the party over the past 6 years, nothing will change.
