I've always registered as an independent too, but when I renewed my drivers license in March somehow they changed me to democrat. So I figured I'd actually try and caucus this year. I looked into it and discovered what a huge mess it was -- a primary just seems so much easier.
Then my sister made All-State High school choir, and they had their concert last night in Ft. Collins. So I kind of had to go to that instead. A primary would have still allowed me to vote, since I could have gone anytime during the day, but the caucus starts at 7 sharp. The clusterf#$k you described sounds about like my expectations.
