Guam elects on the territorial level a governor and a legislature with the governor elected for a four-year term by the people. The Legislature of Guam has fifteen members elected at large in an open primary for two year terms.
The island also holds both Democratic and Republican presidential caucuses every election year, and conducts a presidential straw poll to coincide with the U.S. general election, even though Guam's votes do not officially count in presidential races.
Guam has a multi-party system, with two strong parties.
