The fact is that Ref. C and D were actually addressing real problems that were in part caused by TABOR.
The correct thing to do is acknowledge that TABOR was a great start, but that we've learned some things about it since it was passed, and need to make some changes so that it works better. That will prevent things like C and D from getting traction in the future.
The incorrect thing to do is to whine about it, because that only plays into the Democrats' hands.
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.
