The stricter Colorado cap does three things: it imposes firm spending caps (which grow only to reflect population and inflation), returns any excess revenues to taxpayers and allows only voters, not legislators, to override the caps.
Both sides agree that the measure reined in the budget. The growth in per capita spending fell to 31 percent in the decade after the cap from 72 percent in the decade before, according to the Independence Institute, a Colorado group that favors it.
Supporters say the cap ignited the subsequent economic boom, with low taxes luring businesses. They also say it kept the state from overspending when flush only to face painful cuts later. “Tabor saved Colorado’s fiscal fanny,” said Jon Caldara, the institute’s president……
Another major fight is under way in California, where Gov. Arnold Schwarzenegger has pushed an antispending provision onto the fall ballot, albeit one seemingly less strict than that of Colorado.
In Maine, a veteran tax opponent, Mary Adams, is gathering signatures to put a spending cap on the ballot next year. And last year, the leader of the Wisconsin Senate, Mary Panzer, a moderate Republican, delayed convening a special session to consider a spending cap. That drew a primary challenge from a conservative rival, Glenn Grothman, who defeated her in what Mr. Norquist calls a watershed moment.
