DENVER - An income tax question to be decided by Colorado voters Tuesday sets up a watershed change for how public schools are funded and could be the largest voter-approved tax hike in state history.
But Amendment 66 is so complicated that many voters don't understand it.
The ballot measure rewrites Colorado's School Finance Act to correct funding imbalances that state education officials say have grown worse over time. The proposal would raise income taxes an estimated $950 million a year. It would also revive a progressive income tax structure Colorado abandoned in the 1980s.
Supporters of the measure have raised more than $10 million to promote it. Still, the measure's prospects are far from certain.
