Denver (AP) Supporters of a ban on affirmative action in public institutions say they've collected enough signatures to get the issue on this fall's ballot.
Backers have collected nearly 129,000 signatures, about 50,000 more than required by law. The secretary of state will review them to make sure at least 76,000 are from registered voters.
The measure says the state may not use race, color, sex, ethnicity or national origin to discriminate against anyone or to give anyone preferential treatment.
It would apply to public hiring and contracts and to public education.
California businessman Ward Connerly is backing the proposal and similar measures in four other states. He thinks the Colorado campaign will cost about $2 million raised inside and out of the state.
