Guam is governed by a popularly elected governor and a unicameral 15-member legislature, whose members are known as senators. Guam elects one non-voting delegate, currently Democrat Madeleine Z. Bordallo, to the United States House of Representatives. U.S. citizens in Guam vote in a straw poll for their choice in the U.S. Presidential general election, but since Guam has no votes in the Electoral College, the poll has no real effect. However, in sending delegates to the Republican and Democratic national conventions, Guam does have influence in the national presidential race. These delegates are elected by local party conventions.
