Volunteer
The county party posts the work it needs: events, voter contact, and campaign help. The county clerk runs a separate, nonpartisan election-judge program.
For party work, start at the Boulder County Republicans Take Action page. That is the official list. Events on this site’s calendar are copied from public pages, including that party’s calendar.
Election judges are hired and trained by the Boulder County Clerk. Poll watchers are a party role. Pick the official page that matches the job. Do not assume a party volunteer shift and a clerk’s election-judge shift are the same thing.
