DENVER (AP) A Denver judge has upheld a ballot question seeking to raise Colorado residents' income taxes to benefit public schools.
Opponents of Amendment 66 sued to have the measure deemed invalid. They argued there were enough suspect petition signatures to call the Nov. 5 measure into question.
The school tax proposal would raise about $950 million a year.
If passed, the additional income tax money would be spent on expanded access to free preschool and other upgrades.
Opponents say the overhaul doesn't make the right kinds of changes to improve schools.
