Voters in Colorado and Nebraska -- who approved putting the measure on the ballot on Friday -- will decide in November whether to eliminate affirmative action, a program that increases the number of minorities and women in government and education.
"Colorado has been labeled a purple state," Ward Connerly, an advocate of the ban, told USA Today. "It'll depend on how much money is spent and how the measure is framed."
There were not enough signatures in Arizona, Missouri or Oklahoma to put the measure on the ballot but proponents of the ban are optimistic about the chances of it passing in Colorado, a swing state. So far the campaign committee has spent $3 million.
