为在预选会中胜出，候选人需要有愿意花上数小时来为其站台、并说服他人加入的支持者。 胜出的候选人可以指望根基深厚的坚定支持者。随着选举日的临近，这些支持者往往会帮助候选人竞选。

对预选会的主要不满在于预选会时间太长，因此将很多必须工作或有其他职责在身的选民排除在外。同时，因为预选会是公开的，人们可能会在表达对某一候选人的偏好时感到公众压力。这与在初选中投票是非常不同的。初选的投票是不公开的。

#US-Primaries – Caucuses: Advantages & Disadvantages.

In order to win in a caucus, a candidate has to have supporters who are willing to spend hours explaining their support and convincing others to join them.

Those who win can point to a strong base of dedicated supporters who will often then help campaign for the candidate as Election Day nears.

A key complaint about caucuses is that they are too long, leaving out many voters who have to work or have other responsibilities.

Also, because caucuses are public, people may feel public pressure in a caucus to support one candidate over another.

This is very different than casting a ballot in a primary, which is done in private.
