Jay Bullock has posted an excellent TABOR/TPA timeline over at folkbum's rambles and rants that helps to bring some focus to the argument about restricting revenues artificially. PMac at the MJS took issue with parts of that post and Jay has that discussion up as well.
Buried in the comments of that second post Sven has given the best analogy for the Bride of TABOR that I have seen. I'm going to change it just the tiniest bit here.
Imagine that you are driving your car down the Interstate and it starts to sputter. You pull over to the shoulder and take out the owners manual. There is a pamphlet tucked inside, half the length of the manual itself, which says, "Put in less gas."
