Colorado's Taxpayer's Bill of Rights (TABOR) has the reputation of being America's best and most effective fiscal limit. However, it is under attack once again. On Election Day, Colorado residents will vote on Amendment 59 which would permanently nullify TABOR's revenue limit by requiring that all surplus revenues be spent on schools. This is an important election for fiscal conservatives. If Amendment 59 wins, TABOR will likely be reduced to a historical footnote. A defeat of Amendment 59, however, would have implications that will be felt well beyond Colorado. Indeed, a revitalized TABOR could give fiscal conservatives something that they have lacked--an effective model that can be used in other states.
