Voter information
How the primary works
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Wyoming utilizes a closed primary process.[2][3]
For information about which offices are nominated via primary election, see this article.

In Wyoming, all polling places are open from 7 a.m. to 7 p.m. Mountain Time. An individual who is in line at the time polls close must be allowed to vote.[4]
