CO ballots, in Larimer county, also have a stub with “Track your ballot online at votelarimer.org” on it. I voted in the primary a couple of weeks ago and tried to use the Tracker yesterday. Couldn’t find any info on the Larimer country website about my ballot.
Found a link to “Track Your Ballot” but it took me to “find your registration” which led me to a way to change my registration info and nothing else.
At least for me it is a scam. No way to track my ballot at all.
I was able to track it for you!
