In November, Colorado voters will decide if Arapahoe Park will be allowed to add casino-type gambling.
The Denver Post reports Colorado Secretary of State Scott Gessler determined enough signatures had been submitted in support of allowing such a vote.
The paper said the issue will ask voters to authorize limited-stakes gaming at horse racetracks in Arapahoe, Mesa, and Pueblo counties. Currently, Arapahoe Park in Aurora is the only horse racetrack in operation in those counties.
