BallotTrax system has gone live — on Monday, voters who have been added automatically to the system will receive a text or email to let them know they are enrolled; this will be an opt out system. Moving forward, those voters that use the service will receive updates via phone, text, or mail. Voters can check if they are enrolled at: colorado.ballottrax.net. It is available to voters in all 64 counties except Denver, which has their system at ballotrace.org
