Colorado's secretary of state says it's a problem with "national repercussions." He's declaring many of the state's electronic voting machines unreliable.
The decision affects six of Colorado's 10 most populous counties. Electronic voting machines used in Denver, Arapahoe, Pueblo, Mesa and Elbert counties can't be used in the upcoming 2008 primary because of problems with accuracy and security.
A number of electronic scanners used to count ballots were also decertified.
When new rules for testing the voting machines were adopted in March, the secretary of state required the four electronic voting systems used in all 64 Colorado counties to apply for recertification. Only one system had all its equipment pass muster.
