After some time, the electioneering is temporarily halted, and the supporters for each candidate (and for "uncommitted") are counted. At this point, the caucus officials determine which candidates or groups are viable, potentially including the "uncommitted" group. Depending on the number of county delegates to be elected, the viability threshold is no less than 15% of attendees. "(For four or more delegates, the threshold is 15%. For three delegates, the threshold is the total number of voters, divided by 6, roughly 16.66%. For two delegates, the threshold is 25%. For one delegate, there is no threshold, and the delegate is elected by a majority vote of eligible voters in attendance, following the first round of alignment.)" For a candidate (or the "uncommitted" group) to earn any delegates from a particular precinct, the candidate or group must have the support of at least the percentage of participants required by the viability threshold. Once viability is determined, participants have an opportunity to realign: although supporters of viable candidates or groups are locked into their choice, the supporters of nonviable candidates or groups may find a viable candidate or group to support, join together with supporters of another nonviable candidate or group to secure a delegate for one of the two, or abstain. This realignment is a distinction of caucuses in that (unlike in most primaries) a voter's second choice can help a candidate.
